Magnets are not an infinite source of energy because they follow the laws of thermodynamics, which state that energy cannot be created or destroyed, only transformed. This means that magnets can only convert energy from one …
Because magnets do not contain energy — but they can help control it… In 1841, German physician and physicist Julius von Mayer coined what was to become known as a first law of thermodynamics: “Energy can be neither created nor destroyed,” he wrote.

Both items stick to vertical surfaces. If you look up the basic definitions of energy, force, and work you will see why a magnet does not have infinite energy. What Drakkith said. Work or Energy = force x distance. The magnet doesn't move so the distance is zero and the energy expended is zero.
“Magnetism is a force, but it has no energy of its own,” says David Cohen-Tanugi, vice president of the MIT Energy Club and a John S. Hennessy Fellow in MIT’s Materials Science and Engineering department. Still, he adds, “magnetism is extremely useful for converting energy from one form to another.
Such a machine would not serve as a source of energy but could have utility as a perpetual energy storage device. The seemingly mysterious ability of magnets to influence motion at a distance without any apparent energy source has long appealed to inventors.
If you removed all magnets, yes, then this thing would rotate for eternity, due to conservation of impulse / energy. With the magnets, it will halt pretty soon. Magnets don't create energy. They CAN convert it from electric energy to mechanical, and vice versa.

Dave - Okay. In order to create a magnet, you''ve actually got to put some energy in in the first place, including for a permanent magnet. You''ve got to align all the atomic magnets inside the piece of iron and rotate them so their individual magnetic fields all add together. That takes some energy to do initially, but once that state is in place, you don''t …
There is no infinite energy to be obtained, only way to get magnets to output energy constantly is to put energy into them. Like say burning coal, heating steam, having the steam rotate magnets, and then getting electricity out for as long as you can keep inputting coal. And if you are thinking static force for creating energy, that doesn''t ...
In generators, we are not taking energy out of the magnetic field. The energy going into electrical current is actually coming from the energy used to spin the coil. Scientists call...

Magnets don''t create energy. They CAN convert it from electric energy to mechanical, and vice versa. So you can put work into spinning those moving magnets, and generate electricity in a coil ... or put electricity in a coil and (with the right timings) it''ll move those magnets. Look for Perendev machine.
MRAM is a type of memory that uses magnetic fields to store data, offering non-volatile storage that retains information even when power is off. Why is magnetic storage durable? Magnetic storage is durable because the magnetic states used to store data are stable and do not degrade over time, making it ideal for long-term storage.
Magnets do not violate the law of conservation of energy because they do not create energy, they simply convert one form of energy (such as electrical energy) into another form (such as magnetic energy).
High-energy magnets without REEs have not been produced. To use PMs without relying on rare-earth elements (REEs), options include ferrites, alnico, and Fe-Co-C …
All magnetic fields store some energy which can be generated from a permanent magnet or electromagnet. Permanent magnets made from hard alloys, create their magnetic field …
Neodymium magnets can corrode due to high humidity, further reducing their magnetic strength. To prevent this, store them in a dry and well-ventilated area. Magnetic Fields. Strong external magnetic fields can influence the magnetic properties of neodymium magnets. Store them away from other magnets or devices that generate strong magnetic fields.

High-energy magnets without REEs have not been produced. To use PMs without relying on rare-earth elements (REEs), options include ferrites, alnico, and Fe-Co-C (iron–cobalt–carbon) magnets. However, these alternatives do not achieve the magnetic properties of REE-based magnets. Over the past decade, significant scientific effort has been …
No, magnets do not store any energy within them, therefore no energy can be extracted from them to generate electricity. A common scam is the production of a magnetic motor, where the "inventor" claims that the generator is being powered by magnets, when in fact it is being powered by a hidden battery or hand crank. Reply reply cnash • Magnets are used for renewable …
All magnetic fields store some energy which can be generated from a permanent magnet or electromagnet. Permanent magnets made from hard alloys, create their magnetic field occupying the empty space around them and which does not change. But electromagnets formed using coils of wire create a variable magnetic field around themselves based on the number of coil turns, …
Q.1. Why aren''t magnets used for energy? Ans. Magnets are not used as energy because they do not inherently possess any energy. For example, in a generator, we do not get energy from the magnetic field. The energy going into the electrical current comes from the energy required to spin the coil between the two magnets.
Why can''t magnetism be used as a source of energy? Because magnets do not contain energy — but they can help control it… By Sarah Jensen. In 1841, German physician and physicist Julius von Mayer coined what was to become known as a first law of thermodynamics: "Energy can be neither created nor destroyed," he wrote.
Magnets play a vital role in renewable power generation, converting kinetic energy into electricity through their unique properties. Here is how magnets contribute to the production of renewable power: Wind turbines: Magnets are used in wind turbines to convert the kinetic energy of wind into electrical power. As the wind blows, it causes the ...
Gravity is pulling you toward the ground, but the chair is not expending any energy in keeping you up. Sticking something to a vertical surface (the fridge) is not much different. Whether you use a magnet, of an adesive, you definitely have a force that is compensating gravity, but as long as the object is not moving energy has been used.
Unlike traditional energy sources, which often require extensive mining or drilling, magnetic energy taps into existing materials, reducing the environmental impact of extraction. Lower …
The device simply could not work: any magnet strong enough to pull the ball up the ramp would necessarily be too powerful to allow it to drop through the hole. Faced with this problem, more …
"Magnetism is a force, but it has no energy of its own," says David Cohen-Tanugi SM ''12. Still, he adds, "magnetism is extremely useful for converting energy from one form to another. About 99 percent of the power generated from fossil fuels, nuclear and hydroelectric energy, and wind comes from systems that use magnetism in the ...
If the energy used to create a magnet were instead use to drive a motor, I suspect more energy would be put into the motor than of we found a way to get that energy back out of the magnet and into a motor somehow. Every time energy is transferred some is lost, so I don''t expect magnet-motors to take over the energy sector. Possible is not necessarily practical.
Antiferromagnets could be incorporated into future memory chips that store and process more data while using less energy and taking up a fraction of the space of existing devices, owing to the stability of magnetic domains. "Generally, such antiferromagnetic materials are not easy to control," Gedik says. "Now we have some knobs to be ...
If you have a hill, you can use some energy to put a marble on top, then the marble will roll down. But it takes more energy to reset it and move that marble back up to the top. You can set things up by using energy so a magnet and/or iron can move. But it takes more energy to reset it and get them to move again.
The device simply could not work: any magnet strong enough to pull the ball up the ramp would necessarily be too powerful to allow it to drop through the hole. Faced with this problem, more modern versions typically use a series of ramps and magnets, positioned so the ball is to be handed off from one magnet to another as it moves. The problem ...
