JEE Main 2026 — Magnetic Effects of Current Question with Solution
JEE Main 2026 (21 January Shift 1)
Question
A current carrying solenoid is placed vertically and a particle of mass with charge is released from rest. The particle moves along the axis of solenoid. If is acceleration due to gravity then the acceleration (a) of the charged particle will satisfy :

Correct answer
D
Step-by-step explanation
Inside a solenoid, magnetic field is uniform and parallel to the axis.
Particle moves along the axis, so velocity is parallel to .
Magnetic force (since )
Only gravity acts on the particle.
