Understanding Magnetic Dipole Moments: A Beginner's Guide

AI Thread Summary
Magnetic dipole moments are fundamental concepts in electromagnetism, representing the magnetic strength and orientation of a loop carrying current. They arise from moving charges, creating a magnetic field around the loop, which can be identified as north and south poles using the right-hand thumb rule. The magnetic dipole moment is calculated as the product of the area enclosed by the loop and the current flowing through it. It is classified as a vector quantity, indicating both magnitude and direction. Understanding these principles is essential for grasping more complex electromagnetic theories.

i want to learn about magnetic dipole moments but don't have a good grasp on it
 
Physics news on Phys.org
Ummm... ok. Griffith's text on electrodynamics is a good reference.
 
thanks
 
Hi,

You consider circular wire through which some current is flowing.As you know that moving charge creates magnetic field surround it.
Now you will find two poles as north and south pole which behaves as magnet.(according to right hand thumb rule u can find in which direction (w.r.t the loop) the poles are).
Magnetic dipole moment is the product of the area enclosed by loop and the strength of current in it.
It's a vector quantity.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
