Practice question · True or false
Diamagnetism occurs only in materials that have no permanent magnetic moments.
Hints
- Is diamagnetism an induced response or one that needs pre-existing moments?
- It is induced by the applied field itself, so nothing needs to be there beforehand.
Show the answer
False
Why
False, diamagnetism is a universal induced response opposing any change in field, present in every material including strongly paramagnetic ones. It is simply masked when stronger effects are also present, not absent.
