SATHEE: Moving Charges and Magnetism

Moving Charges and Magnetism - Result Question 13

13. A charged paritcle (charge $q$ ) is moving in a circle of radius $R$ with uniform speed $v$ . The associated magnetic moment $μ$ is given by

(a) $q v R^{2}$

(b) $q v R^{2} / 2$

(d) $q v R / 2$

Show Answer

Answer:

Correct Answer: 13. (d)

Solution:

(d) Magnetic moment, $m = I A$

$= \frac{q v}{2 π R} (π R^{2}) = \frac{q v R}{2}$

$[∵ I = \frac{q}{T} .$ and $. T = \frac{2 π R}{v}]$
