Motion of Charged Particle in a Magnetic Field | Moving Charges and Magnetism Class 12, JEE & NEET

When a charged particle moves along a magnetic field line into a region where the field becomes stronger, the particle experiences a force that reduces the component of velocity parallel to the field. This force slows the motion along the field line and here reverses it, forming a Magnetic Mirror. The motion of a charged particle in a magnetic field is characterized by the change in the direction of motion. It is expected also as the magnetic field is capable of only changing the direction of mo...
