A magnet made of a material that keeps its magnetism is called?
Permanet Magnet
Is magnetite a magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
Which of the following can be done to demagnetize a permanent magnet?
To demagnetize a permanent magnet, you can subject it to high temperatures, apply an alternating current (AC) magnetic field, or strike it with a hammer. These methods disrupt the alignment of magnetic domains within the material, causing the magnetism to be lost.
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.
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 permanent magnet and a temporary magnet be made from the same magnetic material?
no they can not.
A magnet made of a material that keeps its magnetism is called?
Permanet Magnet
When all of the magnet domains line up on their own the material is called?
a permanent magnet
What is a lifting magnet?
A lifting magnet is an electromagnet that is meant to hold or move material that comes in contact with the magnet. This is the opposite of a traction magnet.
What is the process or material that determines what makes a permanent magnet?
The material and process that determine what makes a permanent magnet is the alignment of magnetic domains within the material. When these domains are aligned in the same direction, the material becomes magnetized and exhibits magnetic properties.
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 are some ways of creating a permanent magnet?
One way to create a permanent magnet is by aligning magnetic domains in a ferromagnetic material by exposing it to a strong magnetic field and then cooling it to set the alignment. Another method involves rubbing a piece of iron or steel along a magnet to align the domains in the material and create a weak permanent magnet.
What is the best procedure to create a permanent magnet?
The best procedure to create a permanent magnet is to expose a ferromagnetic material to a strong magnetic field for an extended period of time, aligning the magnetic domains within the material to create a permanent magnetic field.
Which magnetic material can retain permanent magnetization?
False permanent magnets can but electromagnets need a running current A+
Were is the charged particle flow in a permanent magnet?
I believe it is in the material. It says that everything has charged particles in it. It also says that in order for a material to be magnetic, then, its atoms have to line up in a certain way so that the electrons in the material all have the same general motion. So if it's a permanent magnet, then the charged particles would be in the material.
How are magnets used in fridge door works?
They basically work just like any other permanent magnet. The magnet, and the magnetic material (iron-based) in the refrigerator, attract one another.
What is a pernanent magnet?
You may mean 'permanent' in which case it's a material which retains it's magnetic field, unlike a temporary magnet.
