yes, magnets slowly lose their power over time, in optimum conditions, this is about 1% every 10 years, but i have no idea of the rate of decay of the magnetic field in less than optimum conditions.

∙ 11y agopermanent magnets are called Ferro magnets. These magnets retain their magnetic properties even after removing of magnetic field. It will have Suceptability > 1. Ex : Iron, cobalt, nickel.
Para magnets exhibits magnetism in magnetic field, but loose its magnetic properties when field is removed. Ex : Magnesium, molybdinum, lithium, Tantalum.

∙ 14y agoIn a magnet the individual magnetic fields of the atoms or molecules are lined up in the same direction. Various things, including thermal motion, can result in this alignment becoming more randomized, resulting in a reduced magnetic field strength.

What types of magnets are temporary?
Electromagnets. They are generally required to loose their magnetism, as soon as the power is removed. This is done by using a soft iron core or laminated plates.
How do you power a fan with magnets?
You can power a fan by putting magnets on all the flaps that make the air then put another magnet near it to make it move and the repel of the magnets will create movement.
How does a bullet train get its power?
A bullet train gets it's power from extremely powerful magnets. The magnets are on the sides of the track, and train.
How is Law of electric charge related to electric motor?
An electric motor is made up of magnets .. some electric induced magnets , some permanent magnets . the electric magnets are arranged so that when the power is turned on they activate in a series of pulsing magnets.. this pulsing causes the magnets in the core and the magnets in the body of the motor to repel and attract as magnets will do .. this repelling and attracting causes the magnets to try and chase each other around .. this action is turning the core of the motor and producing the rotating action expected from an electric motor
How could you increase a magnet's power without using electricity?
By rubbing two magnets together.
Why don't magnets lose their pulling power over time?
they actually do loose their magnetism but it takes about 20 years
Why are magnets kept in the keepers?
when magnets are kept loose their magnetic power becomes weak. therefore a non magnetic substance should be kept in between of two magnets while storing them. so that there is no continuous attraction or repulsion between them.
What type of magnets are easy to magnetize but Loose made quickly?
electronic magnets as they work with electricity produced
What types of magnets are temporary?
Electromagnets. They are generally required to loose their magnetism, as soon as the power is removed. This is done by using a soft iron core or laminated plates.
What is the boiling point of magnetism?
There is the Currie point where magnets loose their magnetism.
What stops the pulling power of magnets?
I dont think you can ---- If you super-heat the magnets, it will demagnetize them, thus stopping the "pulling power" of the magnets. Basically stick the magnets in a vat of super boiling water, that should be sufficient enough heat to demagnetize the magnets.
Why do big magnets pick up little magnets?
because it is bigger than the little magnets and has more power than the little magnets do.
How do you power a fan with magnets?
You can power a fan by putting magnets on all the flaps that make the air then put another magnet near it to make it move and the repel of the magnets will create movement.
How do they power a magnet train?
With magnets
How could you increase a magnets power without electricity?

What is the Industrial Magnets?
Industrial strength magnets are used widely for lifting, work holders,and chucks.
