An electromagnet is positioned on a table in the east-west direction. Electric current eventually flows through the coils of the electromagnet in the direction shown, but initially there is no current. A compass is placed a few centimeters east of the electromagnet. At first the compass is pointing north.

As the current increases to a very large amount, in which of the following directions will the north end of the compass face?

A

East.

B

West.

C
