Permanent Magnets Vs. Temporary Magnets

When it comes to magnets, there are two main categories: classified as permanent and temporary. While the details and characteristics of temporary magnets were described in the previous section, permanent magnets are worth mentioning as well.

In order to give you a better understanding of what exactly a temporary magnet is, we will be conducting a direct comparison between temporary and permanent magnets. Take a look at the table down below to get a general idea of how they compare, and keep reading for more of the details.

Temporary Magnets Permanent Magnets
Do not have the ability to retain their magnetic force on their own Always retain their magnetic field/force
Require another magnetic field to have power Do not require force from another magnet to have power
Magnetic materials are considered to be hard Magnetic materials are considered to be hard
Able to function through magnetic force or electric current (stops working in the absence) Usually created with another strong magnetic force (magnet becomes permanent as a result)

Permanent Magnets Vs. Temporary Magnets

As you can probably guess by just reading the names, a permanent magnet is essentially the opposite of a temporary magnet, for obvious reasons.

We now know that temporary magnets are generally weaker than their counterparts, and require the presence of a stronger magnetic force in order to function properly. So, as you might already be wondering, what exactly are permanent magnets?

Permanent magnets are given the name “permanent” due to the fact that the electrons inside of the given object have been permanently magnetized. This means, on a more atomic level, that the electrons inside will not change directions, and will continue to provide this level of magnetism indefinitely.

These two magnets are much more different in the way that they work, aside from the names that we refer to them as. The materials that make up a temporary magnet are much softer in comparison to the much harder permanent magnet.

To give you a better idea of what a permanent magnet is, think about the most basic disc magnet that goes on your refrigerator. Upon examination, you will notice that the material is extremely hard and solid.

Throughout the remainder of this section, refer to this image when you hear the term permanent magnet, in order to get the best understanding of the concept.

Moving on, the strength of a temporary magnet pales in comparison to that of a permanent magnet, as mentioned in the previous section. To be more specific, temporary magnets will only possess ionic energy when in contact with a much stronger magnetic field.

This is achieved through a stronger magnetic force or an electric current moving through a set of coils inside of the temporary magnet. In the same way that this gives the magnet a powerful force, it is taken away completely in the absence of this current.

In summary, temporary magnets have lower magnetic fields that ultimately become intertwined with stronger ones, before being removed from the alternate field.
