WebNov 20, 2024 · The coins are shown to exert force as a result of magnets moving in this manner. The magnetic force is strongest at the poles and weakest at the center. A magnet, on the other hand, has the ability to exert a magnetic field. When we bring two magnets near the north or south poles of the poles, one of them will repel the other. WebSep 3, 2024 · In macroscopic EM theory is that magnetic force on magnetized body element free of in-bulk electric current (basic nonconductive magnet) is given by the formula: F = − m ⋅ ∇ B e x t. Thus force is non-zero only if the magnetic field varies with position in space.

Magnets exert forces and torques on each other due to the rules of electromagnetism. The forces of attraction field of magnets are due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of fundamental particles (such as electrons) that make up the material. Both of these are modeled quite well as tiny loops of current called magnetic dipoles that produce their own magnetic field and are affected by external magnetic fiel… WebA magnet is surrounded by a magnetic field which pushes or pulls other magnets and things made of iron, nickel or cobalt that are located within it.
