Question

What does fingers and thumb represent in Right Hand Rule 2 (RHR 2)?

1) Magnitude of the current
2) Force experienced on the wire
3) Direction of the current
4) Magnetic field direction

Answer 1

The thumb in RHR-2 represents the direction of the current, whereas the fingers represent the direction of the magnetic field loops induced by the current.

Step-by-step explanation:

In the Right Hand Rule 2 (RHR-2), which is used to determine the direction of the magnetic field induced by a current-carrying wire, the thumb represents the direction of the current, and the fingers of the curled hand represent the direction of the magnetic field loops. So, when you point the thumb of your right hand in the direction of the current, the direction in which your fingers curl will be the direction of the magnetic field loops surrounding the wire.
