A length of wire is bent into a closed loop and a magnet is plunged into it, inducing a voltage and,consequently, a current in the wire. A second lenghtof wire, twice as long, is bent into two loops of wire, and a magnet is similarly plunged into it. Twice the voltage is induced, but the current is the same as that produced in the single loop. why?
The second wire has twice the resistance of the first wire. Although voltage doubles, current stays the same.
