All of the following factors affect the torque acting on a current carrying coil placed in amagnetic field EXCEPT
Correct answer: A. electric field.
- A. electric field.
- B. area of the loop.
- C. amount of the current.
- D. direction of the current.
Explanation
A) electric field: The formula for torque on a current-carrying coil in a magnetic field does not involve the electric field. The torque is a result of the interaction between the magnetic field and the magnetic dipole moment created by the current in the coil. Therefore, an electric field does not directly affect this torque.

About Magnetic Flux Density
Magnetic flux density measures the magnetic force acting on a current carrying conductor or moving charge in a magnetic field. Work includes the relations B equals F divided by IL and F equals qvB, the tesla as its SI unit, field direction and the distinction between flux density and magnetic flux.
