Question 87: Magnetism and Matter

Question

A charge particle moving in magnetic field B, has the components of velocity along B as well as perpendicular to B. The path of the charge particle will be

Accepted Answer

When a charged particle moves in a magnetic field, its motion is affected by the components of its velocity that are parallel and perpendicular to the magnetic field.
The component of velocity that is parallel to the magnetic field doesn't get affected by the magnetic field. It causes the particle to move along the magnetic field lines in a straight line.
The component of velocity that is perpendicular to the magnetic field causes the charged particle to move in a circular path around the magnetic field lines due to the magnetic Lorentz force.
Combining these two effects, the charged particle follows a helical path, where the axis of the helix is aligned with the magnetic field.

Answer

helical path with the axis along magnetic field $$\mathrm{B}$$

Answer

straight along the direction of magnetic field $$\mathrm{B}$$

Answer

circular path

Answer

helical path with the axis perpendicular to the direction of magnetic field B
