Answer 2

Magnetic force, $F=q(v\times B)$

Explanation:

There exists a force when a charged particle is moving in the magnetic field. The magnetic force is given by :

$F=q(v\times B)$

Here

q is the charged particle

v is the speed of particle

B is the magnetic field

$\theta$ is the angle between magnetic field and the velocity of the charged particle.

Tesla or T is the SI unit of magnetic field. It is also known as Weber per meter square.
