Question

A wire 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

Answer 1

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

Answer 2

(D) circles around the wire that go in at the bottom

Step-by-step explanation:

The direction of magnetic field can be determined by using right hand rule. This rule states that if the thumb shows the electric current, then the curled finger will give the direction of magnetic field.

In this case, a wire has a current that flows to the right. According to right hand rule, the direction of magnetic field will be given by curled finger i.e. circles around the wire that go in at the bottom.

Hence, the correct option is (D) circles around the wire that go in at the bottom.
