Question

Will the interaction of the current through the loop with the magnetic field cause the loop to rotate?

Answer 1

Current flowing through wire loops within a magnetic field generates torque, causing the loops to rotate, thus converting electrical energy into mechanical work. If a bar magnet moves through a wire loop, a current is induced due to the changing magnetic field.

Step-by-step explanation:

When current is passed through wire loops within a magnetic field, the interaction of the current with the magnetic field exerts a torque on the loops. This interaction causes the loops, and hence the attached shaft, to rotate. This is the fundamental principle behind electric motors, where electrical energy is converted into mechanical work. As the loop rotates, to maintain continuous motion, the current is reversed every half rotation to ensure the torque is always directed in the same way, facilitating constant rotation.

Answer 2

Yes, it will.

Step-by-step explanation:

Using Flemings right hand rule, where the forefinger points to the direction of the magnetic field, the middle finger points in the direction of the current and the thumb gives the direction of force or motion acting on the conductor. One can observe from the attached image that the force on both sides of the ring pull the ring out, which increases the angle. Therefore, the net torque acting on the loop is positive and tends to rotate the loop in the direction of increasing angle θ (counterclockwise).
