The emf induced in a conductor of unit length moving with unit velocity at right angies to a magnetic field is equal to Ivey
Correct answer: A. Magnetic flux density
- A. Magnetic flux density
- B. Torque
- C. Mutual induction
- D. Motional emf
Explanation
According to Faraday's law of electromagnetic induction, the induced electromotive force (emf) in a conductor moving perpendicular to a magnetic field is given by the formula EMF= B.v.l, whereB is the magnetic flux density (also known as magnetic induction),is the velocity of the conductor, and I is the length of the conductor.Therefore, the correct option is (a) Magnetic flux density.

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.
