You can''t create energy out of nowhere. In order to get your wheels turn, you have to provide some amount of energy (obtained from the fuel). If you make electricity from that rotation, it will withdraw energy (and slow the weels). And because no system 100% efficient, some (in fact a lot) of the energy will be lost in the process (as heat). As

Customer ServiceAbout 99 percent of the power generated from fossil fuels, nuclear and hydroelectric energy, and wind comes from systems that use magnetism in the conversion process." Every energy generation technology—with the exception of photovoltaics—relies on spinning turbines that put electrons in motion and push them through circuits and generators.
Customer ServiceMany electromagnets have an advantage over permanent magnets because they can be easily turned on and off, and increasing or decreasing the amount of electricity flowing around the core can control their
Customer ServiceThe magnetic field caused by a magnet, like an electric field caused by charge and a gravitational field caused by mass, can only store energy. They can''t create energy. The magnetic field can convert mechanical energy to electrical energy, but it requires a mechanical
Customer ServiceMagnets 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.
Customer ServiceBasically, the flow of electricity through a wire creates magnetic fields, and certain types of magnetic fields (they have to change with time) cause the flow of electricity. Generators of electricity use magnets to generate the electricity. Electric motors use both electricity and magnets to create motion. The incoming electricity provides the
Customer ServiceElectricity and magnetism are separate yet interconnected phenomena associated with the electromagnetic force. Together, they form the basis for electromagnetism, a key physics discipline. You can have an electric field without a magnetic field, and vice versa. But, a moving electrical charge always has an associated magnetic field, while

Customer ServiceThe fact that you can''t use a magnet as a battery or vice versa is among the reasons why it took people so long to figure out the connection. But a little thought will show this is not proof that the theory is false. Paper is made from trees. A sheet of paper is fundamentally the same "thing" as a tree. But you can''t build a house by taping sheets of paper together, and
Customer ServiceTechnically, conductors can store a small amount of electricity due to their capacitance, which is the ability to store an electric charge. However, this capacitance is very
Customer ServiceElectricity generation using magnets requires the conversion of kinetic energy into electricity, which is then utilized to power various devices. Mainstream power generation methods, including renewables, utilize magnets for energy conversion. However, magnetism alone can''t generate electricity without an external source of energy.
Customer ServiceHowever if there are permanent magnets why can''t they spin an object in perpetuity. But... How? Magnets attract or propel metals. By definition, permanent magnets don''t switch off, so even if you have an object affected by the magnet stuck to the end of a turbine, say, the magnet pushes it away and then what? The turbine won''t spin because the

Crystals have unique properties that make them suitable for storing electricity. They can conduct electricity efficiently, which is why they are widely used in devices like radios, computers, and watches. Another
Customer ServiceAlso we can''t store electricity. We generate it and use it. There is no box we can hold electricity to use it little by little.. Ps: batteries are small generators in essence. They use chemical reactions to generate current. You can''t capture electricity and store it. Reply reply BuckNZahn • What is a battery then?

Customer ServiceThey don''t act like most objects. If you try to push the two north poles or two south poles together, they repel each other. But if you put a north pole and a south pole together, the magnets will stick together because the north and south poles attract each other. Just like protons and electrons—opposites attract in magnets.
Customer ServiceYes, electrical energy is difficult to store. In my opinion for the following reasons: It dissipates fast with explosive reactions in specific situations since it depends crucially on conductivity which can easily be affected by weather or accident. The more electrical energy is stored, the greater the possibility of breakdown of insulation.
Customer ServiceFrom powering our homes and devices, to generating energy for transportation and communication, electromagnetism is at the heart of many essential technologies. Understanding the fundamental relationship between electricity and magnetism allows us to harness its power and use it for our benefit.

Customer ServicePermanent magnets, meanwhile, don''t need a power source since they are naturally ferromagnetic. In other words, maintaining a constant magnetic field needs a continuous power supply in case of electromagnets. Sure an electromagnet can store huge amounts of energy in its magnetic field but the energy will start discharging as soon
Customer ServiceTechnically, conductors can store a small amount of electricity due to their capacitance, which is the ability to store an electric charge. However, this capacitance is very low compared to materials specifically designed for energy storage, making conductors impractical for
Customer ServiceThe magnetic field caused by a magnet, like an electric field caused by charge and a gravitational field caused by mass, can only store energy. They can''t create energy. The magnetic field can convert mechanical energy to electrical energy, but it requires a mechanical energy input. An example is moving a magnet through a coil of

Customer ServiceThere's no kinetic energy in that scenario to take by assumption of being stationary, and the only other potential source of energy - the magnetic field - isn't changing in this case either. The magnetic field caused by a magnet, like an electric field caused by charge and a gravitational field caused by mass, can only store energy.
Yes, electrical energy is difficult to store.

The more electrical energy is stored, the greater the possibility of breakdown of insulation.
Capacitors can store significant amounts of energy. With the development of super-capacitors, this modality of energy storage has already entered the practical, commercial domain. Yes, a piece of metal acts like a capacitor and can store some energy. However the capacitances are too small for practical purposes.
The magnetic field caused by a magnet, like an electric field caused by charge and a gravitational field caused by mass, can only store energy. They can't create energy. The magnetic field can convert mechanical energy to electrical energy, but it requires a mechanical energy input.
The more electrical energy is stored, the greater the possibility of breakdown of insulation. It is as if one built a dam and the water could easily find a hole on the floor or break the dam.
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.
