12th Class Physics Magnetism Question Bank MCQs - Moving Charges and Magnetism

When a charge of 1C moving with velocity 1 m/s normal to a magnetic field experiences a force 1 N, then the magnitude of the magnetic field is

A) 1 Gauss

B) 1 Tesia

C) 1 Orested

D) None of the above

Correct Answer: A

Solution :

Option [a] is correct

Explanation: F = \[qv\operatorname{B}\ \sin \theta \]

When q=1 C, v=1 m/s, F=1 N,\[\theta \]=\[{{90}^{\operatorname{o}}}\], then B = 1T
