Diamagnetism is the property of an object

Petar Mali

Diamagnetism is the property of an object which causes it to create a magnetic field in opposition of an externally applied magnetic field, thus causing a repulsive effect. This is property of all materials. But can be perceive only for materials which atoms or ions have closed shells. Examples: ionic crystals, noble gases...

Why this property can be perceived only for closed shells?

hello for all
i want book about paramagnetism and ferro, dai,anti ferro and ferrite
if you have this book please tell me
thank you

Systems with open shells will have a much stronger paramagnetic response, so the diamagnetic response gets overwhelmed. For a closed shell system, there is no paramagnetic response so only the diamagnetic response is present.

have you tried the hyperphysics website? it's great for basics. for more advanced material maybe try Kittel?
