A 4.00×10-2 Ω square wire loop 35.0 cm on a side has its plane normal to a uniform magnetic field of magnitude B = 2.0 T. If you pull two opposite sides of the loop away from each other, the other two sides automatically draw toward each other, reducing the area enclosed by the loop. a)If the area is reduced to zero in a time of 0.30 s what is the average emf during this time interval? b)What is the average current during this time interval?
