Question

You have a circular loop of wire in the plane of the page with an initial radius of 0.50 m which expands to a radius of 1.00 m . It sits in a constant magnetic field B = 38 mT pointing into the page. Assume the transformation occurs over 1.0 second and no part of the wire exits the field. Also assume an internal resistance of 30 Ω . What average current is produced within the loop and in which direction?

Part A
You have a circular loop of wire in the plane of the page with an initial radius of 0.50 m which expands to a radius of 1.00 m. It sits in a constant magnetic field B = 38 mT pointing into the page. Assume the transformation occurs over 1.0 second
and no part of the wire exits the field. Also assume an internal resistance of 30 2. What average current is produced within the loop and in which direction?
Express your answer with the appropriate units. Enter positive value if the current is clockwise and negative value if the current is counterclockwise.
