Ampere’s Circuit Law

Behavior of Charged particle in the magnetic field

When the charged particle moves through the magnetic field it experiences a force on it. When the charged particle q moves with the velocity v in the magnetic field B and the velocity of the particle is perpendicular to the direction of the magnetic field then force acting on it is given by F = q(v × B). Hence, the magnetic force is directed towards the circular motion of the particle and acts as a centripetal force. Thus if v and B are perpendicular to each other, the particle moves in a circle. Thus, the particle moves in the helical motion when the two components are acting perpendicular. When the particle moves along the direction of the magnetic field then no effect is felt upon it....
