I'm trying to understand why, when, in a solenoid for example, electrical current is magnetically induced, doesnt the newly created magnetic field due to current "cancel out" the effects of the original changing magnetic field. One person I asked suggested resistance, and this sounds completely plausible, but does that mean current can't be magnetically induced in a superconductor? There may be other factors that are immidiately apparent in the equations we're working with but I don't see them. It seems like it would be quite complex, wouldn't one need some way of finding the rate of change of current due to a changing magnetic field? Is it instaneous (if the dB/dt is constant). note: this I'm assuming area is constant (for flux = area * magnetic field)(adsbygoogle = window.adsbygoogle || []).push({});

I suspect my understanding of these concepts is pretty feeble, and so here I am.

edit: mm maybe this would have been better in the "classical physics" section
