A square loop of side a recedes with a uniform velocity u a y , from an infinitely long filament carrying current I along a z shown in below. Assuming that ρ = ρ o at time t=0 , show that the emf induced in the loop at t>0 is ( ) a I a u V o emf + = ρ πρ μ 2 2 2. The conducting cylinder shown below rotates about its axis at 1200 rpm in a radial field given by ρ a B r r 6 = The cylinder, whose radius is 5 cm and height is 10 cm, has sliding contacts at its top and bottoms connected to a voltage meter, determine the induced voltage. 3. The parallel plate capacitor shown above is filled with a lossy dielectric material of relative permittivity ε r and conductivity σ . The separation between the plates is d and each plate is of area A. The capacitor is connected to a time-varying voltage source V(t)....
