The Figure Below Shows A Piece Of Insulated Wire Formed Into The Shape Of A Figure Eight You May Consider The Two Loops 1 (44.45 KiB) Viewed 29 times

The figure below shows a piece of insulated wire formed into the shape of a figure eight. You may consider the two loops of the figure eight to be circles, where the upper loop's radius is 4.00 cm and the lower loop's radius is 8.00 cm. The wire has a uniform resistance per unit length of 8.000/m. The wire lies in a plane that is perpendicular to a uniform magnetic field directed into the page, the magnitude of which is increasing at a constant rate of 2.10 T/s.
