Suppose that when you move the north pole of a bar magnetic toward a coil it induces a positive current in the coil. The strength of the field produced by an electromagnetic can be controlled electronically. Suppose you place a coil near the north pole of an electromagnet and increase the field while keeping everything stationary. Which one of the following will happen?
A positive current will be induced in the coil
A negative current will be induced in the coil
No current will be induced in the coil since there is no relative motion.
