A square frame carrying a current I = 0.90 A is located in the same plane as a long straight wire carrying a current I0 = 5 A, The frame side has a length a = 8 cm. The axis of the frame passing through the mid-point of the opposite sides is parallel to the wire and is separated form it by a distance h = 15 times greater than the side of the frame. Find: (a) ampere force acting on the frame. (b) The mechanical work to be performed in order to turn the frame through 180∘ about its axis, with the current maintained constant.

A coil of radius R carries current i1. Another concentric coil of radius r(r<<R) carries current i2. Planes of two coils are mutually perpendicular and both the coil are free to rotate about common diametre. Find maximum kinetic energy of smaller coil when both the coils are released, masses of coils are M and m, respectively.
