Title: help? physics questions! please
Post by: hyunah on August 05, 2014, 10:51:15 pm
how would I explain using lenz's law that when a iron bar is inserted through a coil with current going through it, the iron bar buzz?

I know Lenz’s Law: the current induced must create a flux opposing this change. something about opposing force? magnetic field?

please and thank you
