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
Step-by-step 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.
