The deadline for flipping Earth's magnetic poles has long passed. Here's how it is threatening lifeEarth has a magnetic field which appears very similar to a bar magnet that has a north and south pole. However, it is not comparatively stable since it gets generated by complex processes which ...
How a Generator Works When an electric current flows through a wire, it generates a three-dimensional magnetic force field around the wire, similar to that surrounding a bar magnet. Magnets are ...
