Find the magnitude of the vector force applied to the coil if its distance from the centre of the loop is equal to x and the vector p_(m) coincides in direction with the axis of the loop.

In the shown figure a current 2i is flowing in a straight conductor and entering along the diameter of the circular loop of similar conductor through the point A. The current is leaving the loop along another similar semi-infinite conductor parallel to the plane of the loop through the point D. what is the magnetic field at the centre of the loop P ?

A: In any magnetic field region the line integral ointvecB.vec(dl) along a closed loop is always zero. R: The magnetic field vecB in the expressioin oint vecB.vec(dl) is due to the currents enclosed only by the loop.
