The Motion of Charged Particles in Magnetic Fields © D Hoult 2008

A charged particle moving parallel to the flux lines

A charged particle moving parallel to the flux lines experiences no force

A charged particle moving parallel to the flux lines experiences no force There are three possible paths for a charged particle moving through a uniform magnetic field

If the angle, q between the field and the direction of motion is zero the path is

If the angle, q between the field and the direction of motion is zero the path is a straight line

If the angle, q between the field and the direction of motion is 90° the path is

If the angle, q between the field and the direction of motion is 90° the path is circular field into plane of diagram

If the angle, q between the field and the direction of motion is 90° the path is circular field into plane of diagram

If the angle, q between the field and the direction of motion is 90° the path is circular field into plane of diagram

If the angle between the field and the direction of motion is 0° < q < 90° the path is

If the angle between the field and the direction of motion is 0° < q < 90° the path is

If the angle between the field and the direction of motion is 0° < q < 90° the path is

If the angle between the field and the direction of motion is 0° < q < 90° the path is a helix
