A square loop of wire of side a is rotating with frequency [tex] \omega [/tex] in a magnetic field. I understand that at time t, a magnetic field [tex]B=B_{0}sin\omega t [/tex] passes through the loop. But why does the current induced in the loop vary twice with the frequency of rotation? What is the expression of the current induced?(adsbygoogle = window.adsbygoogle || []).push({});
