Alright. Firstly, I'm sorry for posting in Advanced Physics forum. This should go to Intro Physics. I didn't know the rules. My apology.
Yes, I know changing magnetic fields produce electric field. Here, in this problem, as the magnetic field is changing with time, the flux linkage with the...
A non conducting ring of mass m and radius R has a charge Q uniformly distributed over its circumference. This ring is placed on a rough horizontal surface such that the plane of the ring is parallel to the surface. A vertical magnetic field B=B0t2 τ is switched on. After 2 second from switching...
