Answer 1

When you move a wire though an electromagnetic field you can induce a current in the wire… The same works the other way where if you “move” the electric or magnetic field relative to the wire it can induce a current in the wire. As well, a current going through a wire will create its own electric and magnetic fields.

Using alternating current (where the direction of the current will flip proportional to its frequency… So if its 60hz then it will change direction 120 times per second) you can create a changing electromagnetic field, if you have 2 wires close together you can induce an alternating current in the other wire. To better induce such a current you add coils.
