  • 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! 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 earth's own magnetic field to generate electricity? This got people thinking. This requires first understanding electricity and magnetism. Electricity and [...]

  • Application of High Performance Sintered NdFeB Magnets in Wind Power Generators

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 at high temperature. The life of the magnet depends on the substrate material and surface anti-corrosion treatment. The anti-corrosion of [...]

  • 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?

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, in case anyone reading this doesn't already know. Electricity (we say "current") is created when charged particles flow, like water [...]
