The video explains the concepts of magnetic, electric, and gravitational fields using simple demonstrations. It shows how ...

Magnetic fields lines are invisible but they fill the space around a magnet where the magnetic forces work on magnetic materials, and where they can attract or repel other magnets. Although we ...

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 ...

This means that their magnetism is there all the time and cannot be turned on or off as it can with an electromagnet. Converting a magnet to a non-magnet is called demagnetisation. Magnets are ...
