Question

State the rule, which governs the direction of the magnetic Lorentz force.

Answer 1

Answer:

Faraday’s law of induction is the fundamental law on which electric motors operate. Michael Faraday is credited with discovering induction in 1831, but James Clerk Maxwell described it mathematically and used it as the foundation of his quantitative electromagnetic theory in the 1860s.

Inductance is a property of a device that tells how effectively it induces an emf in another device (or on itself).

Faraday’s law generally states that in a closed coil (loop) of wire, a change in the magnetic environment of the coil causes a voltage, or emf (electromotive force), to be induced in the coil.

Answer 2

The rules which governs the direction of the magnetic Lorentz force are as follows :

• The Right hand thumb rule governs the direction of the magnetic Lorentz force.
• According to this rule, if the curl of the fingers describes the cross product (v×B), then the thumb gives the direction of the force.

• Also, the direction of Force is always perpendicular to the plane containing Velocity and magnetic field.
