Temporary magnet: good example is an electromagnet. It maintains magnetic attraction only so long as an electric current surrounds it. Permanent magnet: most common. Example: bar magnet. Will maintain magnetic properties for quite a while, although they can be eventually demagnetized.
A material that is easily magnetized tends to lose its magnetism quickly may be called a Temporary Magnet. Most temporary magnets, however, are electromagnets, made of coils of wire , sometimes wrapped around a metal core. An electromagnet looses its magnetism when electric current is not flowing through the coils.
A magnet that is hard to magnetize but tends to keep its magnetism is called, a Permanent Magnet.
Permanent magnets don't lose their magnetism.
Permanent magnets, such as magnetite or rare-earth elements, retain their magnetic properties perpetually, while temporary magnets exhibit magnetic properties only when affected by a magnetic field produced by an electric current or another permanent magnet.
Temporary magnets are those which posses magnetism temporarily eg: electomagnet it shows magnetism till when electricity is passed through it.
Permanent magnets are natural magnets they shows permanent magnetism
Once magnetized, permanent magnets retain their magnetism properties. On the other hand, temporary magnets lose their magnetic ability once they are out of a magnetic field.
A permanent magnet has natural magnetic properties while a temporal magnet is created by artificial means.
The poles of a temporary magnet are not aligned until electricity is passing through the wire.

What is used to test permanent magnet generators?
you get it up to operating speed and see if it delivers full load voltage and current. if it has been severely overloaded the permanent magnet can be discharged causing the output to be low
What is pmg stator?
PMG permanent magnet generator is used for excitation or rotor in altrnator
How can you tell the difference between ALUMNIUM and stainless steel?
Grab a small magnet. It will stick to stainless steel - it won't stick to aluminum.
Can small permanent magnet motors be reverse direction if the direction of current flow to the motor is reverse?
Permanent magnet field motors. With a these motors, a permanent magnet is used to replace the field coil. DC power is connected via the brushes, to the armature only. Reversing the polarity, will cause the motor to reverse its direction of rotation. It is very common to use a switch to intentionally reverse to the polarity, to allow reversal of the motor if desired.
What are the factors causing a permanent magnet generator not to generate emf?
A magnetic field will not generate an EMF if there is no motion, so the primary factor causing a permanent magnet generator to not generate EMF is if it is not turning.
What is the difference between permanent pole and temporary pole?
a Temporary Magnet lose its magnetism quickly, a Permanent Magnet is hard and it keeps it magnetism
What sticks to a temporary magnet?
Anything that is attracted to a permanent magnet will be attracted to (sticks to) a temporary magnet.
Is magnetite a temporary magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
Can a permanent magnet and a temporary magnet be made from the same magnetic material?
no they can not.
How do you make a temporary magnet?
To make a temporary magnet, you can rub a piece of iron or steel with a permanent magnet. This process aligns the magnetic domains in the material, creating a temporary magnetic field. To enhance the temporary magnetism, you can increase the number of times you rub the material with the permanent magnet.
What distinguishes a permanent magnet from a temporary magnet?
A permanent magnet retains its magnetism once it has been magnetized, while a temporary magnet only retains its magnetic properties as long as it is in the presence of a magnetic field. Permanent magnets are made of materials with high magnetic retentivity, such as iron or steel, while temporary magnets are usually made of materials with low magnetic retentivity, like soft iron.
Different between temporary magnet and Parmanent magnet?
A temporary magnet can be magnetized or demagnetized easily, while a permanent magnet retains its magnetization over a long period of time. Temporary magnets are usually made of soft magnetic materials like iron, while permanent magnets are made of hard magnetic materials like neodymium or ferrite. Temporary magnets require an external magnetic field to maintain their magnetism, whereas permanent magnets do not.
What is the difference between permanent magnets and temporary magnets?
One is temporary, the other is more or less permanent.
What is a temporary magnet called?
A temporary magnet is called a soft magnet. It can be easily magnetized and demagnetized, unlike a permanent magnet that retains its magnetism for a longer period of time.
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.
Can you magnetize a magnet in order to change it as a permanent magnet by the use of electricity?
No it will only be possible for it to be a temporary one
Is a bar magnet a temporary magnet or not?
A bar magnet is a permanent magnet, meaning it can hold its magnetic properties for a long time without requiring an external magnetic field to maintain its magnetism.
