Question

Do the direction of magnetic field 'B' and velocity of charged particle entering the magnetic field be always perpendicular? If not how Lorentz force be perpendicular to both magnetic field and velocity?

please give me answer clearly..​

Answer 1

Explanation:

the velocity is not perpendicular to the magnetic field, then v is the component of the velocity perpendicular to the field. The component of the velocity parallel to the field is unaffected, since the magnetic force is zero for motion parallel to the field.

Answer 2

Answer:

The magnetic force is perpendicular to the velocity, and so velocity changes in direction but not magnitude. Uniform circular motion results. The component of the velocity parallel to the field is unaffected, since the magnetic force is zero for motion parallel to the field
