2. A charged particle moving parallel to the flux lines

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

4. 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

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

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

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

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

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

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

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

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

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

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