Magnetics question

2020 · 6 Sep · Shift 2 · Q44

JEE MainPhysicsMagneticsMCQ+4 / −1
A charged particle going around in a circle can be considered to be a current loop. A particle of mass m carrying charge q is moving in a plane with speed v under the influence of magnetic field B→\overrightarrow BB. The magnetic moment of this moving particle:
  1. A
    mv2B→2B2{{m{v^2}\overrightarrow B } \over {2{B^2}}}2B2mv2B​
  2. B
    -mv2B→2B2{{m{v^2}\overrightarrow B } \over {2{B^2}}}2B2mv2B​
  3. C
    -mv2B→B2{{m{v^2}\overrightarrow B } \over {{B^2}}}B2mv2B​
  4. D
    -mv2B→2πB2{{m{v^2}\overrightarrow B } \over {2\pi {B^2}}}2πB2mv2B​
