JEE Main 2016 — Electromagnetic Induction Question with Solution
From: JEE Main 2016 (Online) 10th April Morning Slot
Question
Consider a thin metallic sheet perpendicular to the plane of the paper
moving with speed ‘v’ in a uniform magnetic field B going into the plane of the paper (See figure). If charge densities 1 and 2 are induced on the left and right surfaces, respectively, of the sheet then (ignore fringe effects) :
This question includes a diagram. The text above accompanies the figure.

Correct answer
A1 = 0 B, 2 = 0 B
Step-by-step explanation
Magnetic force on electron
= e
F = eVB [As and are perpendicular]
Also, F = e E
and E =
eVB = e
= VB = 1
as 1 = 2
2 = VB
= e
F = eVB [As and are perpendicular]
Also, F = e E
and E =
eVB = e
= VB = 1
as 1 = 2
2 = VB
