Refer the diagram. A wire carries a current, creating a magnetic field around itself as shown. The current in the wire is:

• Directed to the right

• Directed to the left

• Equal to the magnetic field

• n the same direction as the magnetic field

If a current runs through the coil from A to B, the bar magnet will ---.

• be attracted to the coil

• be repelled from the coil

• spin counterclockwise

• feel a force directed up the screen
