Question 6 (5 marks) A DC motor of square coil ABCD with sides 10.0 ch consists of 100 turns. It is rotated in the field of a
uniform permanent magnet of field strength 20 mT, as shown in Figure 5. The current in the square coil
is 500 mA.
Figure 5
In the position shown, what is the magnitude of the net force on the arms AB?
