1. (20 points) Consider a toroid of made of N square loops of wires (side length a) with current i. The mean radius of the toroid is R. You may express your results in terms ofN, R,a, i, and natural constants. Use Ampere's Law, prove that the magnetic field at a point inside the toroid and a distance r from the center is given by ue Ni/ (2 r). Find the magnetic flux through the cross section of the toroid....

Question 4 10 pts The force constant of a spring is 500 N/m and its unstretched length is 16 cm. The spring is placed inside a smooth tube that is 16 cm tall (Figure a). A 0.57-kg disk is lowered onto the spring (Figure b). An external force P pushes the disk down further, until the spring is 6.4 cm long (Figure c). The external force is removed, the disk is projected upward and it emerges from the tube (Figured)....

3. (60pts) A rectangular, conducting, wire loop of sides L and W, total mass m, and total resistance R initially lies in the horizontal ry-plane, with corners at (x, y, z) = (0,0,0), (0,W.0), (L,0,0), and (L, W.0). There is a uniform, upward magnetic field B = Bk in the space within and around the loop. The side of the loop that extends from (0,0,0) to (L,0,0) is held in place on the x-axis;...

3. Electromagnetic Inductance. Consider a single loop under magnetic field. (a) If the area A = 0.012[m) is constant, but the magnetic field is increasing at the rate of 0.020 T/s), determine the induced emf. (Use Faraday's law; the induced emf in a loop equals the absolute value of the time rate of change of the magnetic flux through the loop.) (b) If the total resistance of the circuit is 5.0(82), find the induced current. (c) Suppose we change the...
