What else can I help you with?
What are magnets that do not require any power of force to maintain their field called?
They are called permanent magnets. These magnets retain their magnetic field without the need for any external power source or force to maintain them.
Do magnets lose power over time?
Yes, magnets can lose their power over time due to factors such as exposure to heat, moisture, and physical damage.
What types of magnets are temporary?
Temporary magnets include electromagnets and soft magnets. Electromagnets are made by passing electric current through a coil of wire wrapped around a magnetic core, and their magnetism can be turned on and off by controlling the electric current. Soft magnets are materials that can be easily magnetized but lose their magnetism quickly once the external magnetic field is removed.
What power source uses the rotation of giant magnets to create electricity which is then directed to the outlets in people's homes?
The power source that uses the rotation of giant magnets to create electricity is a hydroelectric power plant. In these plants, water flow turns turbines attached to generators with large magnets, which convert mechanical energy into electrical energy that is then transmitted to homes and businesses through power lines.
What are the differences between electromagnets and permanent magnets, and how do they function differently?
Electromagnets are temporary magnets created by passing an electric current through a coil of wire, while permanent magnets are naturally occurring magnets that retain their magnetism without an external power source. Electromagnets can be turned on and off by controlling the electric current, while permanent magnets always have a magnetic field.
Why don't magnets lose their pulling power over time?
they actually do loose their magnetism but it takes about 20 years
What type of magnets are easy to magnetize but Loose made quickly?
electronic magnets as they work with electricity produced
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 they power a magnet train?
With magnets
How could you increase a magnets power without electricity?
By rubbing two magnets together.
What is the Industrial Magnets?
Industrial strength magnets are used widely for lifting, work holders,and chucks.
Do all magnets have the same amount of power?
No, not all magnets have the same power. The strength of a magnet is determined by its magnetic field, which can vary depending on factors like the material it's made of and its size. Magnets can range from weak refrigerator magnets to strong neodymium magnets.
What are magnets that do not require any power of force to maintain their field called?
They are called permanent magnets. These magnets retain their magnetic field without the need for any external power source or force to maintain them.
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.
Do hot or cold magnets have more power?
Cold. If magnets get overheated, they can cease to work all-together.
How does magnetism help us in your lifes?
magnets help us because magnets can help power your refrigerator.
