Answer:A loop with an AC current
produces a changing magnetic
field. Two loops have the same
area, but one is made of plastic and
the other copper. In which of the
loops is the induced voltage
greater. A loop with an AC current produces
a changing magnetic field.
Consider a copper loop and next to
it, imagine a loop of air of equal
size. In which of the loops will the
induced electric field be greater.
Explanation: does this make since
