In the diagram below, what do the three numbered vectors represent?

Explanation:

The right hand rule is used to find the magnetic force acting on a charged particle in the magnetic field. The magnetic force is given by :

Where

I is the current

B is the magnetic field

In this type of rule, the magnetic field, the electric current and the force are mutually perpendicular to each other.

In the given figure,

Vector 1 represent the magnetic field

Vector 2 represents the electric current

Vector 3 represents the force

what is the question because that is not a question.
