Magnetic Force on Charged Particle in a Solenoid | Class 12 Physics Problem Solution

In this video, we break down a classic physics problem involving a current-carrying vertical solenoid and a charged particle.The Problem:A current-carrying solenoid is placed vertically, and a particle of mass $m$ with charge $Q$ is released from rest. The particle moves along the axis of the solenoid. If $g$ is the acceleration due to gravity, what will be the acceleration ($a$) of the charged particle?What you will learn in this video:How the magnetic field behaves along the axis of a vertical solenoid.The formula for the magnetic Lorentz force ($\vec{F} = Q(\vec{v} \times \vec{B})$).Why the angle between the velocity vector and the magnetic field vector dictates the net magnetic force here.Step-by-step reasoning to determine the correct relation between $a$ and $g$.
