no coz a intilization is required by every component

Answer

Yes, it can but, fortunately, it only happens occasionally. When this happens, it's necessary to demagnetise the field poles by passing an external d.c. current through the field windings. This process is known as 'flashing the field'.

Will a magnet still be a magnet if it is melted?

A magnet is produced by aligning the magnetic domains in a material to point in the same direction. When heated, the magnet loses its magnetism as the molecular motion, which is caused by heating, destroys the alignment of the magnetic domains. Ferromagnetic materials also lose its magnetism after being melted. However, when the magnet is being hammered whilst cooling in a magnetic field, the melted magnet would gain its magnetism again.


When will a permanent magnet lose magnetism?

a permanent magnet has its domains arranged in one direction at all times and is thus able to exercise magnetic properties at all times, but it loses its magnetism if it is heated to a certain extentsecond way is to hammer it constantly. this disrupts the alignment of the domains (i.e. they are originally aligned in the same direction) and causes them to align in different directions thus destroying the magnetic behavior of the magnetic.If their microcrystalline structure or chemical composition change, they tend to no longer be magnetic.


Do magnets lose their magnatism when heated?

In depends upon how hot you are talking about. Cold would be my best answer in general. If you are comparing the magnetism between say 10 below zero and 100 F then there would be no discernable difference. If you should heat the metal to red-hot, the magnetism would be lost after the metal has cooled.


How can magnetism be destroyed?

---- Magnetism can be destroyed by following methods:---- * By heating the magnet, * By hammering the magnet.--->In accordance to this point...allowing the magnet to fall violently* By keeping similar poles of magnets together for a long time. * [not sure about this]by keeping magnet under running water.


What is the definition of a permanent magnet?

The permanent magnet generator is a synchronous machine where the rotor windings has been replaced with permanent magnets. This eliminates the excitation loses in the rotor, which otherwise typically represent 20-30% of the total generator loses. The reduced losses also give a lower temperature rise in the generator, which means that a smaller and simpler cooling system can be used. The temperature reduction in the rotor also reduces the temperature in the bearings, improving reliability by increasing the lifetime of the bearing and bearing grease.

Can a motor lose residual magnetism in the stator and if so how can it be restored?

Yes it can be restored by priming the generator set using a 12 volt battery. Connect the battery in right polarity to the slip rings. The generator must be run first, as soon as the voltmeter register rising voltage disconnect the battery immediately.


A permanet magnet will lose magnetism?

over time it will lose its magnetism. It will also lose its magnetism if it is temperature is to high or when it's vibrate too much.

Do magnets lose their magnetism over time?

Yes, magnets can lose their magnetism over time due to factors such as exposure to heat, physical damage, or demagnetizing fields.


Can the rock magnetite lose its magnetism?

Yes, rocks containing magnetite can lose their magnetism over time due to various geological processes such as heating, cooling, or chemical alteration. These processes can disrupt the alignment of magnetic domains within the magnetite crystals, leading to a loss of magnetism.


How to cause a magnet to lost its magnetic power?

A magnet can lose its magnetism if exposed to high temperatures. If heated above the point called the Curie temperature, a magnet will lose its magnetism.
