Answer:
In order to produce a magnetic field an electric charge must be in movement.
Explanation:
A magnetic field is generated by the movement of a charged particle in the space around it, as can be seen in the following equation:
[tex]B = \frac{F}{qvsen \theta}[/tex] (1)
Where F is the magnetic force, q is the charge of the particle, v is its velocity and [tex]\theta[/tex] is the angle between B and v.
Therefore, in order to produce a magnetic field, it is necessary for the electric charge to be in movement.
When a charge is moving with velocity v it produces some kind of wave near it due to which some kind of force is observeed.In order to produce a magnetic field an electric charge must be moving.
It is the type of field where the magnetic force is obtained. With the help of a magnetic field. The magnetic force is obtained it is the field felt around a moving electric charge.
The number of magnetic flux lines on a unit area passing perpendicular to the given line direction is known as induced magnetic field strength .it is denoted by B.
As we know that current is directly propotional to the induced magnetic field greater the current I, the greater the magnetic field B. The amount of current flow in the wire depends upon the moving charges.
Hence in order to produce a magnetic field, an electric charge must be moving.
