JEE Main 2016 — Magnetic Effects of Current Question with Solution

JEE Main 2016 (09 Apr Online)

Question

A magnetic dipole is acted upon by two magnetic fields which are inclined to each other at an angle of 75o. One of the fields has a magnitude of 15 mT. The dipole attains stable equilibrium at an angle of 30o with this field. The magnitude of the other field (in mT) is close to

Correct answer
B11

Step-by-step explanation

θ 1 +θ= 75 o

M B 1 sin θ 1 =M B 2 sinθ

⇒ B 1 2 = 15 2

⇒ B 1 = 15 2 ≈11 mT
