Question

In an electric motor coil is placed in a magnetic field. When an electric current is started to flow through a coil immediately this coil feels the action of magnetic forces that are provided the rotation or the coil. On the figure 5 below a wire rectangle CMND with an axle A0A1 is placed in a magnetic field of 0.750 T so that the magnetic field is directed along the rectangle's plane from the left to the right. Determine the directions and values of magnetic forces acting on each side of the rectangle loop if its sides CM = DN = 0.40 m, CD = MN = 0.15 m, and an electric current in this loop is 0.45 A. Explain what forces are responsible for the loop's rotation. Solution:

Explanation / Answer

magnetic force, F=i*l*B

F=0.45 A * 0.40 m * 0.75 T

=0.135 N
