A loop wire with radius r =0.015m is in a magnetic field with magnitude B as shown in the figure. 

B changes from B1 =0.55T to B2 = 6.5T in at a constant rate. The resistance of the wire R = 5 ohm. 

a) Express the magnetic flux  going through a loop of radius r assuming a constant magnetic field B. 

b) Express the magnetic flux change, in terms of B1 and B2 and r.

c) Calculate the numerical value of in T-m2.

d) Express the magnitude of the average emf E induced in the loop in terms of and .
