A 20-kilometer metal rope was thrown into the ionosphere to harness geomagnetism in space
A 20-kilometer metal rope was thrown into the ionosphere to harness geomagnetism in space In 1996, the US Space Shuttle Columbia released a tethered satellite in space. A nearly 20-kilometer-long conductive rope was connected between [...]
Magnetism can generate electricity! Why don’t people use the Earth’s own large magnetic field to generate electricity?
Magnetism can generate electricity! Why don't people use the Earth's own large magnetic field to generate electricity? Magnetism can generate electricity, which is a major law known to all. But why can't people use the [...]
Application of High Performance Sintered NdFeB Magnets in Wind Power Generators
Application of High Performance Sintered NdFeB Magnets in Wind Power Generators Abstract: The permanent magnet wind turbine adopts high-performance sintered NdFeB permanent magnets, and the high enough coercive force can prevent the magnets from demagnetization [...]
Why don’t we use the magnetic field provided by the earth to generate electricity?
Why don't we use the magnetic field provided by the earth to generate electricity? It sounds like a good idea, but it's not very practical. Before we explain why, let's understand how we generate electricity, [...]
