A loop of wire with radius r=0.071 m is in a magnetic field with magnitude B.B changes from B1=0.43 T to B2=8.5 T in t=7.5 s at a constant rate.Randomized Variablesr=0.071 mB1=0.43 TB2=8.5 TΔt=7.5s a. Express the magnetic flux Φ going through a loop of radius r assuming a constant magnetic field B,b. Express the change in the magnetic flux going through this loop, ΔΦ, in terms of B1,B21,2 and r,c. Calculate the numerical value of ΔΦ in T⋅m2,d. Express the magnitude of the average induced electric field, E, induced in the loop in terms of ΔΦ,r,, and Δt,e. Calculate the numerical value of E in N/C.
