Question

Classroom question charged particle in a uniform magnetic field.

1. Which component of the velocity is responsible for the force acting on the charge particle inside the magnetic field

2. How someone could conclude from Lorenz force formula that charge would be moving in a circular path. Explain

3. Does the newton's 3rd law of motion exist for Lorenz force

4. Can a charge execute complete rotation in a magnetic field if it is thrown outside the magnetic field

5. If an electron is projected with high velocity what would be the possible deviation of radius if special relativity is considered. Bigger or smaller. Can anyone help me with these questions guys.​ Is any one watching this plz try it​

Answer 1

Answer:

1) The magnitude of the force is F = qvB sinθ where θ is the angle < 180 degrees between the velocity and the magnetic field. This implies that the magnetic force on a stationary charge or a charge moving parallel to the magnetic field is zero. 3. The direction of the force is given by the right hand rule.
