What is the difference between a permanent magnet and a temporary magnet?

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.

∙ 7y agoA 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.

∙ 14y agoPermanent 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.

∙ 12y agoTemporary 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

∙ 9y agoOnce 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.

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 is the difference between permanent magnets and temporary magnets?
One is temporary, the other is more or less permanent.
What distinguishes a permanent magnet from a temporary magnet?
Permanent magnets do not lose their magnetic ability. Temporary magnets, however, gain magnetic properties when they are touched or moved by a permanent magnet. The properties of a temporary magnet dissipates over time after the permanent magnet is removed.
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.
Permanent and temporary magnets?
A temporary magnet is something that has been magnetized that won't stay a magnet for long, such as a paperclip that you have rubbed with a magnet. A Permanent magnet is usually a Lodestone that is found naturally or is manufactured by a company. Permanent magnets are always magnetic.
Are permanent magnets are used in doorbells?
no it is not . a temporary magnet is used instead. If you use a permanent magnet, the doorbell will keep on ringing
Are permanent magnets used in doorbells?
no it is not . a temporary magnet is used instead. If you use a permanent magnet, the doorbell will keep on ringing
What is the difference between a permanent and non permanent magnet?
Permanent magnets are bar magnets or horse shoe magnets which has magnetism at all times. But non permanent also known as temporary magnets are usually electromagnets which would have magnetism only when current flows through the coil that surrounds it.
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
Compare an electromagnet and a permanent magnet?
See compare and contrast permanent vs. temporary magnet. Unless, of course, they are truly two different questions.
