Hello everyone, this is my first post at Physics Forums!(adsbygoogle = window.adsbygoogle || []).push({});

I am trying to understand electromagnetism, and when it comes to the magnetic moment, when reading around I see [tex]\mu = IA[/tex] where A is area of a loop, which is an expression I can sort of understand. But when reading about magnetic drifts (I am a little confused for the moment) I see [tex]\mu = \frac{m v^2}{2 B}[/tex]. I am sure both refer to the same value but I cannot visualise how.

Would someone be kind enough to explain this to me?

Thank you!

# Why are there 2 definitions of Magnetic Moment?
