Refer to the actuator of Figure P18.16. The entire device is made of sheet steel. The coil has 2,000 turns. The armature is stationary so that the length of the air gaps, g = 10 mm, is fixed. A direct current passing through the coil produces a flux density of 1.2 T in the gaps. Assume ?r = 4,000 for sheet steel. Determine:
a. The coil current.
b. The energy stored in the air gaps.
c. The energy stored in the steel.
