Learn what a fishing magnet is and how to start magnet fishing. Discover the types, costs, legal considerations, and safety tips for this growing outdoor hobby.

A Halbach array can technically work with as few as 4 magnets. But most practical applications use 8 or more for optimal performance.

Halbach arrays have critical drawbacks: complex assembly, self‑demagnetization, heat sensitivity, high cost, and limited use cases. Learn when to avoid them.

Discover what is the principle of Halbach array – a 90-degree magnet rotation creating 2x stronger fields on one side. Used in maglev trains, motors, and even fridge magnets.

For most Halbach arrays, a two-part structural epoxy delivers the required shear strength and gap-filling. Learn top adhesive choices, critical surface-prep, curing rules, risks, and recommended reinforcement paths.

Halbach arrays concentrate flux on one side but are difficult to build. Learn the five main assembly challenges (repulsion, snap risk, torque, adhesives, precision), real-world techniques, common mistakes, when to hire pros, and practical recommendations for safer, higher‑success assembly.

Halbach arrays concentrate up to ~95% of field on one side and can boost flux density (e.g., 579 mT → 833 mT) and power density vs normal arrays, but cost, assembly complexity and high‑temperature demagnetization are key limits. Use Halbach for weight- and efficiency-critical systems; use normal arrays where cost and manufacturing simplicity matter.

Yes — Halbach arrays are permanent magnets arranged to concentrate field on one side and cancel it on the other. Learn practical limits, common failure modes (tolerance, mechanical forces, temperature), recommended selection steps (specify field, simulate, prototype, partner with experts) and which array type fits motors, MRI, maglev or generators.
