Can you provide examples of paramagnetic and diamagnetic substances and explain the differences between them?

Paramagnetic substances are those that are weakly attracted to a magnetic field, such as oxygen and aluminum. Diamagnetic substances, on the other hand, are weakly repelled by a magnetic field, like copper and bismuth. The key difference between them lies in their response to magnetic fields: paramagnetic substances are attracted, while diamagnetic substances are repelled.
