Permanent Magnet vs. Temporary Magnet: What's the Difference?
Edited by Huma Saeed || By Sumera Saeed || Updated on October 18, 2023
A permanent magnet retains its magnetism indefinitely, while a temporary magnet loses its magnetism when the inducing field is removed.
Key Differences
A permanent magnet is a material that remains magnetic without external influence, while a temporary magnet becomes magnetized only in the presence of a magnetic field.

Permanent magnets are made of materials like ferrite or rare earth metals that intrinsically possess magnetic properties. Temporary magnets, on the other hand, are often made of soft iron or steel and only exhibit magnetism when subjected to an external magnetic field.

Over time, permanent magnets can retain their magnetic properties, maintaining their attraction or repulsion effects. Temporary magnets, conversely, will lose their magnetism after the external magnetic influence is taken away, returning to their non-magnetic state.

The applications of permanent magnets are vast, ranging from refrigerator magnets to components in electric motors. Temporary magnets find use in electromagnets, where the magnetic property can be controlled, like in doorbells or cranes.

While permanent magnets can be weakened or demagnetized by excessive heat or opposing magnetic fields, temporary magnets rely on external conditions, reverting to a non-magnetic state when those conditions change.
