A square wire loop 21 cm on a side, with resistance 37 m2, has its plane normal to a uniform magnetic field of magnitude B = 4.4 T. If you pull two opposite sides of the loop away from each other, the other two sides automatically draw toward each other, reducing the area enclosed by the loop. If the area is reduced to zero in time At = 0.40 s, what are (a) the average emf and (b) the average...
A square wire loop 30 cm on a side, with resistance 39 mΩ, has its plane normal to a uniform magnetic field of magnitude B = 5.0 T. If you pull two opposite sides of the loop away from each other, the other two sides automatically draw toward each other, reducing the area enclosed by the loop. If the area is reduced to zero in time Δt = 0.44 s, what are (a) the average emf and (b) the average...
