A conducting loop of area 240cm^2 and resistance 14(Ohm symbol) lies at right angles to a spatially uniform magnetic field. The loop carries an induced current of 320mA .(adsbygoogle = window.adsbygoogle || []).push({});

At what rate is the magnetic field changing?

dB/dt= T/s

Ok.....

So, I use Faraday's Law

Which is That "E" Symbol..=d(magnetic Flux)_B_/dt

Im given resistance so Im assuming I can use the formula I=E/R ....I have R(14) and the induced current which is 320mA...

So I can find "E"....

But what do I do from there....Im pretty lost on this stuff....@_@

Thankyou.
