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

<p>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.</p> <ol> <li><p>The component of velocity that is parallel to the magnetic field doesn&#39;t get affected by the magnetic field. It causes the particle to move along the magnetic field lines in a straight line.</p> </li> <li><p>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.</p> </li> </ol> <p>Combining these two effects, the charged particle follows a helical path, where the axis of the helix is aligned with the magnetic field.</p>
