Batteries and magnets are part of our everyday lives, but what happens\u2002when they are brought together? Can a strong magnet secretly\u2002siphon power from your phone battery? We’re going to take a\u2002closer look at the science behind these everyday objects and explain why there’s no need to freak out.<\/p>

A battery is a\u2002small box that contains electricity and which powered up and let out electricity. Inside a battery, two separate materials known as electrodes each of which lacks one or more electrons, are respectively positive and negative. The two electrodes are sitting in\u2002a chemical solution called an electrolyte. When the battery is linked to a load, a chemical reaction takes place within\u2002the battery. The electrochemical process forces electrons to flow through conductors, which\u2002creates electricity.<\/p>

A magnet\u2002creates a magnetic field that interacts with some materials, such as iron, and can be used to push or pull it. Within each magnet, power appears in the\u2002form of north and south poles, around which tiny particles called electrons orbit within atoms. It is this flow of electrons that generates\u2002magnetic force. We<\/a> can look into batteries and\u2002magnets now that we know their structures.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Electricity and magnetism might seem like two very different things, but <\/span>electricity and magnetism are closely related. Flowing electrons produce a magnetic field, and spinning magnets cause an electric current to flow. Electromagnetism is the interaction of these two important forces<\/span>. Let\u2019s break it down in a simple way.<\/span><\/p>

Electricity is all about electric charges. It is <\/strong><\/span>a form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.<\/strong> Electricity is made up of electric charges, whether they are movement flows\u2002(dynamic form), or not (static form). When it comes to electric charges, there are two types of such\u2002charges: positive and negative. Charges with opposite signs are attracted to one another (like, positive is attracted\u2002to negative); and charges with the same sign repel each other (positive repels positive and negative repels negative). Electric stuff appears in many different ways; it’s\u2002seen in lightning, power that comes out of walls and batteries, and the zap we experience after shuffling around in a carpet and touching something metallic. Any charges at rest give rise\u2002to an electric field, and any that are in motion, just as when they spread in current-carrying conductors, produce magnetic fields. Electricity is usually expressed in\u2002units of current (amps), voltage (volts) and power (watts).<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other.<\/strong> <\/span>Magnetism results from the movement of electric charges. Yes, any movement of charge results in a magnetic field. Like electricity, magnetism has the ability to attract and repel. All magnets have two sides: a north pole and a\u2002south pole. Unlike poles attract each other\u2002and like poles repel.<\/span><\/p>

We can find magnetism in various\u2002technologies for example: a compass, permanent magnets, speakers and electric motors. The earth also\u2002has a magnetic field on which the working of the compasses is based. There are even specialized units to quantify magnetism,\u2002such as the tesla for magnetic strength and the henry for inductance.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Electricity and magnetism are essentially two aspects of the same thing, because a changing electric field creates a magnetic field, and a changing magnetic field creates an electric field. (This is why physicists usually refer to “electromagnetism” or “electromagnetic” forces together, rather than separately.) <\/span>But for much of history, scientists thought electricity\u2002and magnetism were two distinct forces. Electricity was the power that ran lights and machines, magnetism was\u2002what caused compass needles to swivel and allowed magnets to cling to the refrigerator. But everything changed in 1820, when a <\/span>Danish scientist named Hans Christian Oersted made a surprising discovery<\/span><\/a> that changed science forever.<\/span><\/p>

Oersted was delivering a lecture and he just happened to have a compass on hand near a wire\u2002with a battery. When he turned on the battery\u2002and electric current flowed through the wire, the compass needle moved, even without any magnets on or near it! That simple observation demonstrated that when an electric\u2002current flows, it produces a magnetic field. It was the first \u201cdirect experimental evidence that electricity and magnetism are\u2002interconnected,\u201d Dr. Bishop said. Until then, everyone had supposed that electricity could generate\u2002magnetism.<\/span><\/p>

Oersted\u2019s discovery paved\u2002the way for a new area of physics. As scientists advanced, people began to ask whether magnetism, too,\u2002could beget electricity. Subsequent scientists including Michael Faraday and James\u2002Clerk Maxwell proved that a time-varying magnetic field does indeed induce an electric current in a wire. This effect, called electromagnetic induction, is a\u2002key component of many of the technological devices we rely on.<\/span><\/p>

\"The<\/p>

The close relationships linking electricity and magnetism\u2002is known today as electromagnetism. It reveals\u2002that the two aforementioned forces are not independent as many others may think. In reality, they are just two different manifestations of\u2002a single force known as electromagnetic force, one of the four fundamental forces in nature. James Clerk Maxwell later developed a set of equations (<\/span>called Maxwell’s equations<\/span><\/a>) that described how electric and magnetic fields work together and influence each other. His work proved that electric and magnetic fields can travel through space in the form of waves, which we now call electromagnetic waves, including visible light, radio waves, microwaves, and more.<\/span><\/p>

In simple words we can say that, <\/span>Electricity and magnetism are essentially two aspects of the same thing, because a changing electric field creates a magnetic field, and a changing magnetic field creates an electric field.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

This is a typical and intriguing question: Can a powerful\u2002magnet drain a battery? Magnets and\u2002batteries are both connected by the phenomenon of electromagnetism, and it\u2019s reasonable to think that putting a magnet near a battery would drain its energy. The short answer is no; a strong magnet will not drain even a cell phone\u2002battery. <\/span>The magnetism of the magnet does not affect the chemical reaction inside the battery, and the chemical reaction inside the battery and the charge at the pole distance set will not affect the magnet either.<\/b> Now let\u2019s have a closer look at why that\u2019s the case and what can happen when magnets and batteries interact.<\/span><\/p>

\"Can<\/p>

We already know that a battery stores chemical energy, which is converted into electrical energy when the battery is plugged into a circuit. There are a positive and a negative termina,l which are both placed inside the battery. They are both made of metal, and there is also an electrolyte. The chemical reaction generates a current because there is a closed circuit. In simple words, there is a flow of electrons from the negative terminal out of the positive terminal, and in this way, it powers various devices like mobile phones, flashlights, remote controls, and so on.<\/span><\/p>

It is crucial to note that static magnetic fields, like those of permanent magnets, for instance, neodymium magnets, do not have any substantial impact on a battery. Also, these static fields do not bring about any power drain that can be identified. Only a change in the magnetic field\u2014sometimes referred to as the magnetic flux\u2014can initiate electric currents in a conductor. Therefore, unless the magnetic field is static and fluctuating, it will not impact the battery or use energy.<\/span><\/p>

Electric current or the flow of electrons occurs only when the battery is in a closed loop. To put it differently, the battery must be attached to some device that permits the flow of electricity. If the battery is left alone, disconnected from wires or devices, no current is produced and no energy is consumed. This will not change regardless of how strong a nearby magnet is.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

A magnet by itself does not affect the battery\u2019s chemical process or steal its stored energy. However, there are some cases where a magnet might have an indirect effect on a battery, depending on the situation:<\/span><\/p>

Magnetic Fields Can Influence Moving Charges (But Only If Current Is Flowing)<\/h3>

In the scenario where wiring is part of a closed circuit, like inside a magnetic field generator or a motor, there is already an electric current flowing through the wires. A bolt of powerful magnetic force can greatly affect the working charges in the wires and some components. For instance, it may change the flow of current, which is what occurs in electric motors, or even override the precision instruments of some electronics. This scenario describes impact on the device rather than the battery. Even though the battery in this case still only discharges power according to the voltage level required by the burden circuit.<\/span><\/p>

Magnets Can Create Currents, But Only With Movement<\/h3>

Electricity is generated or produced only when a magnet is in proximity to a conductor of some sort \u2013 a wire or coil \u2013 and moves, or it is the magnetic field which moves. The process is known as electromagnetic induction, and it explains why moving a magnet next to a battery that isn\u2019t connected to anything doesn\u2019t result in anything. If a moving magnet is placed next to a coil of wire, generator-like movement can allow a small electric current to be produced. It is important to note that you do not \u201cdrain\u201d the battery in this case; instead, “new” electricity is created through motion instead of drawing upon the stored energy in the battery.<\/span><\/p>

Very Strong Magnetic Fields Might Damage Electronics, Not Batteries<\/h3>

It is plausible that electronic components in a device might get damaged due to extremely strong magnetic fields, which is powerful enough to affect someone. Overheating of components may occur if unwanted currents generated through magnetic forces act on sensitive circuits in phones and computers. Once again though, this does not drain the battery. In fact, it causes the device to do more work and malfunction, which shifts battery usage from stable to rapid, making it seem like the magnet is \u201csucking\u201d the battery\u2019s power.<\/span><\/p>

Magnets Near Certain Battery Types: Safety Note<\/h3>

Batteries, mainly lithium-ion, can pose significant risks if subjected to mechanical stresses or elevated temperatures. Numerous powerful magnets, capable of exerting a strong mechanical force, could potentially be harmful. In extreme worst-case scenarios, the behaviour of the battery with additional force can lead to a short circuit or overheating, reaching temperatures that could compromise its sealed environment, posing risks of leakage or fire. While it’s true that a basic magnet doesn’t drain a battery, it is prudent not to place strong magnets directly on batteries, particularly those in soft cases or unshielded, gentle on edges, batteries.<\/span><\/p>
