Magnetostatics 11 : Paramagnetism and Diamagnetism
Channel: Adam Beatty
Date: 11/08/2013

In this video I continue with my tutorials on magnetostatics which is pitched at university undergraduate level. Specifically I discuss paramagnetism and diamagnetism which are magnetism in a body resulting from an applied external magnetic field. Paramagnetism is magnetism (in the same direction as the applied external field) resulting from the torque on electron spins so usually is only found in elements with unpaired electrons. Diamagnetism is oriented against the applied field and results from an increased orbital speed of the electrons. It's weaker than Paramagnetism but seen in all elements. Since it's weaker than Paramagnetism it's usually important for elements with paired electrons.

I hope it's of use!! Thank you for watching and I hope that this matches your requirements. Please feel free to provide feedback via comments and share with your friends.
