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

• A. Directed to the right

• A. Directed to the left

• A. Equal to the magnetic field

• In the same direction as the magnetic field

1) In the figure, using the right hand rule around a solenoid, which of the below statements is correct:

• North Pole is 7 and South pole is 8

• North Pole is 8 and South Pole is 7

• There is no magnet, so no north or south

• The current is flowing in the direction from 7 to 8
