Differentiate between the following.
Temporary magnet and permanent magnet.
Temporary magnet | Permanent 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. |
