An e.m.f. of 50 millivolt is induced in a coil, when the current int eh neighbouring coil changes form 10 ampere to 5 ampere in 0.1s . What is the mutual inductance of the coils?

A current of 10 A is flowing in a long straight wire situated near a rectangular circuit whose two sides oflength 0.2m are parallel to the wire. One of them is at a distance of0.05m and the other at a distance of 0. IOm from the wire. The wire is in the plane of the rectangle. Find the magnetic flux through the rectangular circuit. If the current decays uniformly to zero in 0.02s, fmd the EMF induced in the circuit and indicate the direction in which the induced current flows.
