Saturation is an effect by which any increase in mangetising force produces a feable improvement in magnetic property if the magnetising force is increased beyond a certain limit. This is analogous to the stress-strain curve of a material obeying Hooke's law.
Saturation is of serious concern in electrical engineering that when a Current transformer with a certain ampere rating is fed from a high current source at primary(than it can carry) , the unit can respond at secondary upto the max. magnetic flux carrying capacity of the core and if at such a condition, the secondary if kept open, can produce an unopposed m.m.f which would consequently produce heating of the core and in some cases to the exploding of the CT unit.
The classical equation that relates magnetism with electricity is H x l= NI which can be used for theoretical calculation of mangetic field intensity with a given ampere turn.
However, saturation for an artificial permanent magnet is the max. value of H upto which is can be magnetised, in spite of being exposed to a strong magnetic field for a specific duration.

Is magnetite a magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
A magnet made of a material that keeps its magnetism is called?
Permanet Magnet
What kind of magnet is a magnetized nail?
A magnetized nail is a temporary magnet, known as an induced magnet. It becomes magnetized when it comes into contact with a permanent magnet, aligning its magnetic domains in the same direction. This temporary magnetism can be lost if the nail is no longer in contact with a permanent magnet.
Is iron a permanent magnet?
No, iron is not a permanent magnet. It can be magnetized in the presence of a magnetic field but will lose its magnetism once the external magnetic field is removed. Permanent magnets, on the other hand, retain their magnetism without the need for an external magnetic field.
Is a bar magnet a permanent magnet?
A permanent magnet is a magnet which will keep its magnetism for a very long time and is difficult to change. No, As I think a permanent magnet means they have abilities to hold the magnetism when they are magnetized. Such as Alnico permanent magnets, but in fact, they can be demagnetized,such as high temperature, hit each other,pulse waves, out magnetic field influence...What's more, different permanent magnetic material, have different abilities on holding magnetism,they can be used in different environments. you can find some details from some manufacturers website, to learn some knowledges.
Is the magnet in a compass a permanent magnet or electronic?
A. Compasses typically use a permanent magnet.
Is a needle in a compass a permanent magnet?
Yes, it is a permanent magnet.
Is magnetite a temporary magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
Is the magnet in a compass a permanent magnetic or an electromagnet?
PermanentThere is no source of current in a compass, therefore the magnet is a permanent magnet.
How can a magnet be temporarily magnetized when attached to a permanent magnet?
When a magnet is attached to a permanent magnet, it can become temporarily magnetized by aligning its magnetic domains with the strong magnetic field of the permanent magnet. This alignment causes the magnet to exhibit magnetic properties for a short period of time.
Is a permanent magnet called a hard magnet or a electromagnet?
Perminant magnet
Is the magnet in a compass a permanent or electromagnet?
The magnet in a compass is a permanent magnet. It retains its magnetism without the need for an external electrical current.
Is magnetite a magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
Is the magnet in a compass a permanent magnet or a electromagnet?
It is a permanent magnet. Electromagnets(as the name suggests) requires an electric source to become a magnet, when the power source is turned off it will not function as a magnet.
