Question

Monday Homework Problem 10.5 A circular loop of wire carries current I. The radius of the loop is R. The current produces an average magnetic field through the surface bounded by the loop of magnitude B = , where is a constant. The magnetic field is parallel to the normal of the surface bounded by the loop. Compute the self-inductance of the loop. Select One of the Following (a) 2R (b) 2A1 (e) R2 Monday Homework Problem 10.6 A loop of wire is wound around the outside of a very long solenoid. Both ends of the wire are connected together to form a complete circuit. The current in the solenoid is decreasing with time. Is a current induced in the loop; If so, in what direction? Select One of the Following: (a) No current is induced. (b) The induced current is in the same direction as the solenoid current. (c) The induced current is in the opposite direction as the solenoid current.

Explanation / Answer

Since you didn't mention which one to answer I am answering 1st one

Self Inducance, L = N/I where N = number of turns = Flux I = current

= BA = I*pi*R^2

N = 1

L = *I*pi*R^2/I = *pi*R^2 ----- option c is correct
