    Number of windings for 120-V household circuit?

    A model train requires 6 V to operate. If the primary coil of its transformer has 240 windings, how many windings should the secondary have if the primary is connected to a 120-V household circuit? V1/V2 = N1/N2 my teacher went over this with the class, and said that N2=...

    Why Does a Metal Ring Heat Up in a Changing Magnetic Field?

    If you place a metal ring in a region in where a magnetic field is rapidly alternating, the ring may become hot to your touch. Why? Is it because a changing magnetic field can create electric fields? I AM SO CONFUSED...and it seems so simple?!?
