AIPMT PRELIMS 2007 Physics Magnetic Moment MCQ Question
Type: MCQ-conceptual-Medium-Class 12
A charged particle (charge q) is moving in a circle of radius R with uniform speed v. The associated magnetic moment μ is given by
A
qvR²
B
qvR²/2
C
qvR
D
qvR/2
Correct Answer
Option B
Detailed Explanation
The magnetic moment μ = (qvR²)/(2R) = qvR²/2, as it is the product of current and area of the loop formed by the circular path.
