Question 6

An electric motor has a coil of 6 turns. On one side of the coil, each turn has a straight 32 mm length of conductor at right angles to the magnetic field. The total force on this side of the coil is 0.0144 N when the current in the coil is 0.75 A.

Calculate the magnetic flux density of the field.
