Question

A DC motor's magnet has a magnetic field that ____ the wire loop's magnetic field, therefore causing the loop to rotate.

Answer 1

b. deflects. A DC motor's magnet has a magnetic field that deflects the wire loop's magnetic field, therefore causing the loop to rotate.

When a conductor, through which an electric current passes, is immersed in a magnetic field, it experiences a deflects force according to the Law of Lorentz creating as result that the loop rotate.

Answer 2

A DC motor's magnet has a magnetic field that deflects the wire loop's magnetic field, therefore causing the loop to rotate.

Answer : Option B

Explanation:

It is said that electric field is always associated with the magnetic field and they influence each other. When a wire carrying current is placed near a magnetic compass, the needle present in the compass will deflect showing that there is a magnetic field associated with the set up. Every magnet has a magnetic field associated with it which causes deflection thereby making the loop to rotate.
