Homework Help: Physics. Help please

Posted by Trevon on Wednesday, October 17, 2012 at 3:40pm.

A small permanent magnet is located on the x-axis with the center at <15,0,0>cm. The magnetís North pole is at location <14.5, 0, 0>cm and the South pole is at location <15.5, 0, 0>cm. A current loop is placed in the y-z plane, such that its center is at the origin. It has a radius R=3cm and has a current of 0.6A. Knowing that the magnetic field at the orgin is <0,0,0>T, calucate the magnetic moment of the permanent magnet. Viewing the current loop from the permanent magnetís perspective, what is the direction of the conventional current in the loop, clockwise or counter-clockwise?
