Question

how does earth behave like a bar magnet?

Answer 1

The Earth is similar to a bar magnet because a magnet holds other magnets or metal objects to it. The same concept goes for the Earth. Gravity from Earth holds all objects down unless another force acts upon it.

Answer 2

Explanation:

The Earth acts like a magnet because the Earth itself is a magnet. It is not a perpetual magnet, but an electromagnet. Deep delved in the Earth, melted metal (mostly iron) flows due to heat that causes convection. The magnetic field is produced by electric flows due to the wave of convection currents of melted iron in the Earth's external core driven by heat. the portion of the earth that has magnetic repercussions is called the magnetosphere.
