According to a circular loop with the number of turns 10 and a radius of 4 cm carries a current I. The magnetic moment of 0.1 A circuit * m ^ 2. The plane of the loop is at an angle of 30 ° with the lines of the homogeneous magnetic field with induction 0.126 mT. To determine: magnetic field strength in the center of the circuit; the work done at the turn of the contour of the target position in the position. wherein the angle between the plane and the direction of the contour lines of magnetic field of 60 °.

Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
