Could Earth be an electromagnet? If so how does it work?
The core of the Earth is also an electromagnet. Although the crust is solid, the core of the Earth is surrounded by a mixture of molten iron and nickle. The magnetic field of Earth is caused by currents of electricity that flow in the molten core. ... If the earth rotated faster, it would have a stronger magnetic field.To get a enough current for everybody, you must move a lot of wire through a magnetic field. We do this by spinning a coil (containing many loops of wire) quickly in a strong magnetic field. During each turn of the coil, electrons get a kick from the magnetic field, moving them along. This creates electrical current.
