For the electromagnet of Example 13.9:
a. Calculate the current required to keep the bar in place. (Hint: The air gap becomes zero, and the iron reluctance cannot be neglected.) Assume μr = 1,000, L = 1 m.
b. If the bar is initially 0.1 m away from the electromagnet, what initial current would be required to lift the magnet?
