In an electromagnet the wires get hot due to the flow of what?
What property of the wire account the wire in filament behave differently other wires in the circuit when the current flow?
answ2. The movement of electrons will produce a magnetic field. Whether by the spin of the electron or its movement. All magnetic fields are produced by moving electrons. Even those on the Sun where it is too hot for magnetic materials. When you cause a current flow through a wire, the flow of electrons will induce a magnetic field. Adding an iron core within the coil, will make the magnetic field stronger. This is then…
