Homework Help: Physics

Posted by charlie on Thursday, June 18, 2009 at 12:27pm.

Would someone check this please?

A circular loop of wire of radius 0.10 m and of resistance 2.0 ~ 10−3 is in
a region where there is a uniform magnetic field B.

The field is at 30 to the normal to the plane of the wire loop as shown in Figure 3. The magnitude of the
magnetic field falls at a steady rate from 6.0 ~ 10−2 T to zero in 2.0 seconds.
What is the value of the current flowing round the wire loop while the field is decreasing?

I get 0.8A
