An electric current induced within the body of a conductor when that conductor either moves through a non-uniform magnetic field or in a region where there is a change in magnetic flux is called
Correct answer: A. Induced current
- A. Induced current
- B. Eddy current
- C. Back emf
- D. None of the above
Explanation
The phenomenon described in the question is related to electromagnetic induction. When a conductor moves through a non-uniform magnetic field or experiences a change in magnetic flux, it induces an electromotive force (EMF) in the conductor, leading to the flow of an electric current. This current is referred to as the induced current.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
