Calculate the mutual inductance of a long straight wire and a rectangular frame with sides `a` and `b`. The frame and the wire lie in the same plan, with the side `b` being closent to the wire, separated by a distance `l` from it and oriented parallel to it.

Find the mutual inductance of a straight long wire and a rectangular loop, as shown in the figure.

The mutual inductance between the rectangular loop and the long straight wire as shown in figure is M .

The mutual inductance between the rectangular loop and the long straight wire as shown in figure is M.

A square frame carrying a current I is located in the same plane as a long straight wire carrying a current I_(0) The frame side has a length a. The axis of the frame passing through the midpoints of the opposite sides is parallel to the wire and is separated from it by the distance which is eta times greater than the side of the frame. Find (a) 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 currents maintained constant.

A square frame carrying a current I=0.90A is located in the same plane as a long straight wire carrying a current I_0=5A , The frame side has a length a=8cm . The axis of the frame passing through the mid-point of the opposite sides is parrallel to the wire and is separated form it by a distance h=15 times greater tahn the side of the frame. Find: (a) ampere force acting on the frame. (b) The machanical work to be performed in order to turn the frmae through 180^@ about its axis, with the current maintained constant.
