Iron, steel, nickel and cobalt are magnetic … 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 …

WebFeb 15, 2024 · The value of the electric or magnetic field is a vector —i.e., a quantity having both magnitude and direction. The value of the electric field at a point in space, for example, equals the force that would be exerted on a unit charge at that position in space. Every charged object sets up an electric field in the surrounding space.
