Why diamagnetic material is not repelled

Click For Summary
SUMMARY

Diamagnetic materials exhibit a unique response to external magnetic fields, characterized by their atomic current loops aligning to oppose the applied field. This phenomenon results in a weak repulsion from magnets, as seen with materials like copper. However, the repulsion is not strong enough to cause continuous movement away from the magnet, leading to confusion regarding their behavior. Most materials are classified as diamagnetic, which explains the prevalence of this magnetic behavior.

When an external magnetic field is applied to a diamagnetic materials, their atomic current loops will tend to align in such a way as to oppose the applied field. Diamagnetism is the residual magnetic behavior when materials are neither paramagnetic nor ferromagnetic and most materials are diamagnetic. Why don't these materials keep on repelled by a magnet? (e.g. we do see copper is repelled and fly away from a magnet)

You might want to rewrite this - they seem to be contradicting each other.

Diamagnets are repelled by magnetic fields. However, most diamagnets are weak.
