WebThere is a group of materials known as ferromagnetic materials. This group includes iron, cobalt, nickel, and some alloys of rare earth elements (mainly neodymium and samarium). These ferromagnetic materials can be made … WebThe force due to gravity follows from the interaction between the Earth's mass and any other body that happens to be nearby (the effect extends far beyond the Earth to the Moon and beyond). Unlike gravity, magnetism doesn't work for anthign with mass. Magnetic forces only occur between specific materials (mainly iron and certain iron alloys).

Web$\begingroup$ Because it produces a changing magnetic field. And Maxwell's equations (Faraday's law) teach us that a changing magnetic field results in an electric field, which gives rise to a current in a nearby wire.It's not the magnetic field providing the force, it's the electric field generated by the changing magnetic field. (note that the current vanishes …
