Can magnet-generated light bulbs stay lit all the time?

No. If the magnet and copper wire are in a relatively static state and there is no breaking of the magnetic wire or change in magnetic flux, electricity cannot be generated. If an external force is applied to change the magnetic flux, an external force is used, which is no different from a manual generator. With the help of water flow, this is the principle of hydroelectric generator; with the help of wind flow, this is the principle of wind turbine.

A perpetual motion machine is a machine that does not require external input energy or only requires initial energy to do eternal work. Perpetual motion machines have been discussed and studied throughout history, but many people don't know their significance. In people's imagination, a perpetual motion machine is a mechanical device that can move automatically and continuously, and can equallift heavy objects and accomplish meaningful things. Some people tried to make such a mechanical device in the 13th century, but no one succeeded until the 21st century. This type of machine is impossible to manufacture because it violates the law of conservation of energy and the law of thermodynamics. One way to express the first law of thermodynamics is this: a perpetual motion machine of the first type is impossible.

Is it true that Chinese inventor Wang Chenhe invented the magnetodynamic generator?

1. Electroacoustic devices: All sound-producing equipment such as cell phones, televisions, stereos, and headphones are vibrated by magnets in the form of permanent external magnetic fields, coils, and diaphragms.

2. Electronic equipment: mobile phones, sleeping leather cases for tablets, etc.

3. Many articles such as suitcases and leather cases use magnets to absorb and secure them.

4. Medical Field: MRI is most commonly used in medical examinations. It uses the magnetic field of the human body and the magnetic material carried by the instrument itself to interact with each other to form a detection image to help people see the cause of the disease. Likewise, in other medical methods there are many traces of the application of magnets, such as acupuncture, magnetotherapy, magnetic detectors, etc.

5. In the field of daily electrical appliances, magnets are widely used. Magnets are widely used in induction cookers, microwave ovens and other electrical appliances, allowing them to play a better environmental and safety role.

Detailed information:

< p>In the traditional industrial field, since generators are used for the production of electricity, transformers are used for the transmission of energy, speakers are used for televisions, motors, telephones and radios are used for electrical machines, so too many magnetic instruments and meters are used. steel coil structure, so it can be said that without magnetic materials, electrification becomes impossible.

The most important application of magnets in the medical field is nuclear magnetic resonance. This magnetic resonance imaging technology can be used to diagnose abnormal tissues in the human body and determine diseases. In addition, the interaction between the magnetic field and the meridians of the human body can also enable magnetic therapy. Currently, products such as magnetic pillowsetotherapy and magnetotherapy belts appeared.

Chinese inventor Wang Chenhe invented magnetic power generationThe machine is not real and there is currently no official information to prove it.

Electricity production is influenced by magnetism (the cutting motion of magnetic induction lines). A perpetual motion machine is only a concept and cannot be realized in reality, because the force (energy) will not increase or disappear.

Detailed information:

The interaction force between the electromagnet and the permanent magnet is used as the energy source to drive the conductive bar in order to cut the magnetic field. field lines to generate electrical energy. By periodically changing the magnitude of the input current to the electromagnet, the force of interaction between the magnets becomes a constant force. By changingperiodically the direction of the input current to the electromagnet, the polarity of the electromagnet is. changed periodically, thus achieving the effect of the electromagnet on the permanent magnet. A steady state in which the direction of the force changes periodically but its magnitude remains constant.

In this stable state, the conductive bar also periodically cuts the magnetic field lines under the traction of the traction shaft connected to the permanent magnet. The two ends of the conductor bar are connected to the transformer by wires and. form After completing the loop, the device of the present invention supplies electrical energy to the outside world through the transformer. This is not a perpetual motion machine, it is a technology that uses special energy to produce electricity.
