Would someone check this please?

A circular loop of wire of radius 0.10 m and of resistance 2.0 ~ 10−3 ƒ¶ 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
