Solution

Temporary magnetPermanent magnet
1.Temporary magnets are those that lose their magnetic qualities after the magnetizing force is removed.1. A permanent magnet is one that retains its magnetic properties even after the magnetizing force has been removed..
2.Because an electromagnetic is also a form of temporary magnet, the position of the magnetic poles can be adjusted.2. In permanent magnets, the position of magnetic poles is fixed.
3.Changes in the magnetizing force can also modify the strength of the magnetic field.3. In the event of a permanent magnetic field, the strength of the magnetic field cannot be changed.
4. For it to act as a magnet, the magnetizing force is constantly required. 4. The magnetizing force is only required once, after which it can continue to function as a magnet even after the magnetizing force has been removed.
