## Main Question or Discussion Point

Hey, guys, I encountered this and confused about it.

"In a perfect conductor, an arbitrarily large current can be induced, and the resulting magnetic field exactly cancels the applied field."

But I suppose, according to Faraday's law,the magnitude of emf is the rate of change of magnetic flux, then if its resistance is zero, its current will be very large, so net magnetic flux as well and definitely not zero.

What do you think about it?
