Question

Write Maxwell’s Right hand thumb rule. What should be the angle between magnetic field and current?

Answer 1

Hint: Maxwell’s right hand thumb rule is used to find the direction of the magnetic field in the conductor. The magnetic field of lines originates from the north pole of the magnet and terminates on the south pole of the magnets. The like magnetic poles always repel each other. Opposite magnetic poles always attract each other.

Complete step-by-step answer:

The Maxwell’s right hand thumb rule states that ‘When the conductor is held in your right hand, such that the direction of the thumb points the direction of the current and the curled finger gives the direction of the magnetic finger.’

Suppose the direction of the current is in upward direction, the magnetic field will clockwise.
When the direction of the current is in the downward direction. The direction of the magnetic field will be anticlockwise.

Thus, the direction of the magnetic field and current are mutually perpendicular. So, the angle between the direction of current and magnetic field is $90^{0}$.

Note: The current is the flow of the electrons in the conductor. The direction of the current is always opposite to the direction of the flow of the electrons. The direction of the magnetic field is dependent on the direction of the current.
