Participants exploring the water drop a powerful magnet into a lake or river and then pull it back up. Magnet fishing combines a powerful magnet with a string to attempt to pull something once lost from the bottom of a lake, pond, or river – an old coin, an artifact, or a forgotten tool. While it may seem simple, the “poundage” or pulling force of a fishing magnet in actual use depends on a variety of factors that affect how it performs in different water conditions. Understanding these factors can help you choose the right magnet for your needs, thereby enhancing your magnet fishing experience and your success in retrieving items.
What factors determine the poundage of a fishing magnet?
Now that we have a basic understanding of how magnet fishing works, the actual pulling force of a magnet is more than just buying a bigger magnet. There are a variety of factors that affect the weight a magnet can actually hold when retrieved from the bottom of the water.
- Magnet Grade:Neodymium magnets used in fishing magnets are graded according to their strength, with higher grades having stronger magnetic forces. This means that an N52 magnet will generally have a stronger pull than a lower grade magnet such as an N35 of the same size.
- Magnet Size and Surface Area:Magnets with larger surface areas can increase the chances of firmly grabbing metal objects. More surface area means more potential for direct contact with underwater objects, which improves the grip.
- Contact Surface Quality:A clean, flat surface is ideal for a magnet to firmly grip. Similarly, objects with rough or uneven surfaces will reduce the total contact area of the magnet, which will weaken the magnet’s grip.
- Air Gap and Interference:The distance between the magnet and the target is called the air gap, and it is critical in any magnetic operation. Silt, algae, and even small rocks in the underwater environment can reduce the contact between the magnet and the target metal, which will weaken the pull.
- Water current:Turbulent waters increase the resistance between the retrieved item and the water, indirectly weakening the fishing magnet’s grip on the target object. For strong water currents, a higher poundage magnet is recommended to counteract the resistance and prevent losing the item.
- Pull angle:The lever angle at which the magnet pulls the object affects the force required to lift it. Pulling straight vertically maximizes the magnetic attraction of the fishing magnet compared to pulling at an angle. Practicing proper technique and keeping the rope taut maximizes the magnet’s effectiveness in different fishing environments.
- Target metal characteristics:Not all metals react the same to fishing magnets. Steel and iron have a strong pull on magnets, while aluminum and some alloys are not attracted to fishing magnets. In addition, oddly shaped objects may only partially contact the magnet, reducing its effectiveness.
Understanding these factors that affect the strength of a fishing magnet during actual use can help you choose a more suitable fishing magnet before you start your underwater exploration. How to choose? Keep reading.
How to choose the right fishing magnet?
Magnet fishing is a curious, exciting, and exploratory endeavor. The right fishing magnet can make a huge difference in what we catch from lakes, rivers, and even murky ponds. But what kind of fishing magnet is the right one for this quest? Factors such as pulling strength, magnet coating, water conditions, retrieval goals, and budget all determine how appropriate a fishing magnet is for this activity.
- Understand the pulling strength you need for this magnet fishing activity. The grade and size of the neodymium magnet in the fishing magnet directly affects the maximum pulling force it can support, with higher grade neodymium magnets or larger magnets having stronger magnetic attraction. If you are looking for large iron items such as bicycles, safes, etc., choose a magnet with a strong pulling force, usually 800 pounds or more. However, if you are looking for smaller items such as tools or coins, a lower pulling force (about 300-500 pounds) is usually sufficient.
- Magnet coatings protect and extend the life of the magnet. Most fishing magnets come with a three-layer coating (nickel-copper-nickel) to prevent rust and chipping. If you frequently fish in or need to fish in saltwater, be sure to consider magnets with additional layers, such as epoxy, which can provide additional protection against corrosion. That’s why Osencmag offers custom coatings for its customers.
- Water depth, current strength, and bottom topography can all affect the performance of fishing magnets. If you’re working in shallow, calm waters, even a lighter magnet will work fine. But for deeper or more turbulent waters, using a strong magnet of the largest possible size will help improve your fishing efficiency. Evaluating the water conditions you’ll be facing will ensure smooth magnet fishing. Click here to get professional guidance on using fishing magnets in practice.
- Evaluate the materials you may encounter during your fishing trip. Not all metals are attracted to magnets, and even ferrous metals have different magnetic attractions. Iron and steel are ideal targets because they are highly magnetic, while objects made of aluminum or brass will not stick to fishing magnets. Knowing ahead of time what types of objects your target waters have often been found in the past can help you choose a magnet with the right pull and control balance.
- If you’re a beginner, it’s wise to start with a lighter, easier-to-handle magnet—one that’s not difficult to handle but still has enough pulling force to get you familiar with this fun fishing technique. Intermediate users may need a fishing magnet with a higher pulling force to try more ambitious pulls. And professionals need to configure advanced fishing magnets—such as double-sided magnets or magnets with extremely high pulling force—to increase the probability of successful treasure hunting. By choosing a magnet that matches your experience, you can enjoy the fishing process while ensuring safety.
- Budget determines which fishing magnet we can afford. While there are some affordable fishing magnets that are sufficient for recreational fishing, higher-quality, professional-grade magnets are usually more expensive. Beginners or occasional users don’t need to spend too much money at the beginning. If you plan to use magnet fishing frequently or challenge challenging fishing spots, investing in a durable, high-quality neodymium magnet will be worth it. The right balance between budget and quality is friendly to our wallets.
Taking all of the above into account can help you have a successful and enjoyable magnet fishing experience. Magnet fishing is as much about the journey as it is about discovery, so make sure you have the magnets that make the adventure worthwhile. Also remember that your area supports this sport, as some areas have clear regulations and restrictions on magnet fishing.

Why Are Fishing Magnets Ideal for Metal Recovery?
Fishing magnets are a powerful tool for recovering lost or discarded metals in the water. Instead of using traditional fishing line and hooks, they use a strong magnet attached to a rod that can pull out ferrous metals quickly and efficiently.
What magnet is best for magnet fishing?
Rare earth neodymium magnets are generally best for magnet fishing. Because they are extremely strong, they can attract heavy metal objects underwater.
