A square coil of wire has 10 turns and an area of 20 cm^2. The square coil is located in a variable magnetic field whose behavior is shown on the graph. The magnetic field is directed at an angle of 45° relative to the normal to the plane of the square coil. a. What is the average emf induced in the coil in the time interval from t=7.50 s to 10.0 s? b. If the wire has a resistance of 0.75 Ω determine the induced current for the interval from part (a)?
