A loop of wire with radius » = 0.081 m is in a magnetic field with magnitude B as shown in the graph. B changes from B1 = 0.34 T to B2= 6.5 T in 4t = 7.5 s at a constant rate. Express the magnetic flux Ø going through a loop of radius r assuming a constant magnetic field B. Express the change in the magnetic flux going through this loop, 4Ø, in terms of B 1, B2 and r. Calculate the numerical value of 4$ in T-m². Express the magnitude of the average induced electric field, E, induced in the loop in terms of 49, r and At. E = Calculate the numerical value of E in N/C.
