JEE Main 2023 — Magnetic Effects of Current Question with Solution
JEE Main 2023 (13 Apr Shift 2)
Question
An electron is moving along the positive x-axis. If uniform magnetic field is applied parallel to the negative z-axis, then
A.The electron will experience magnetic force along positive y-axis
B.The electron will experience magnetic force along negative y-axis
C.The electron will not experience any force in magnetic field
D.The electron will continue to move along the positive x-axis
E.The electron will move along circular path in magnetic field

B and E only
Step-by-step explanation
The Lorentz force is given by
So, .
As the magnetic field is perpendicular to the velocity, motion would be circular.
