Scientists Create New Design to Generate Electricity from Earth's Magnetic Field
Nearly 200 years ago, a scientist named Michael Faraday tried experimenting to see whether Earth's magnetic field could help humans generate electricity for practical purposes. He concluded that ...
Magnetism is a natural force, one that works at a distance. Magnets get their force from magnetic fields created by the atoms within the metal. Magnets are useful for things like turbines we use to ...
'A force more powerful than gravity within the Earth': How magnetism locked itself inside our planet
"As the magma cooled to form what is today the world's solid outer crust, magnetism was locked into minerals containing iron, such as magnetite." When you purchase through links on our site, we may ...
