Question

A charge of +10 C enters a uniform magnetic field parallel to its direction. What will happen to the charge?

Answer 1

Magnetic field:

1. A magnetic field is a region around the magnet.
2. The magnetic field which moving the electric charge.
3. It possesses the force of magnetism acts.

A diagram to represent the magnetic field:

Explanation:

As we know that a charged particle's magnetic force is orthogonal to the magnetic field.

So, $F=qvB\sin \theta$

So, in a straight line, there is no net force, and the charged particle goes if its velocity is parallel to the magnetic field.

Therefore, the angle between the magnetic field vector B and the velocity vector forms the force.

And, the magnetic force is equal to $F=qvB\sin \theta$

So, if the velocity and magnetic field are parallel and no force occurs, then in this condition a charged particle can continue to move in a straight line.
