Awire has a current that flows to the right.

which describes the magnetic field produced by the current?

a. straight lines along the wire to the right

b. straight lines along the wire to the left

c. circles around the wire that go in at the top

d. circles around the wire that go in at the bottom

D. circles around the wire that go in at the bottom

Explanation:

In order to determine the direction of the magnetic field around the wire, we should use the right's hand rule. First of all, let's keep in mind that the magnetic field around a current carrying wire consists of concentric circles around the wire, so the only possible options are C and D.

In the right-hand rule, we put our thumb in the same direction of the current (so, toward the right). Then we wrap all the other fingers of the hand around the thumb: the direction of the fingers give the direction of the magnetic field. In this case, the fingers go in at the bottom of the thumb (bottom of the wire), so the correct option is

D. circles around the wire that go in at the bottom
