Energy comes in many forms. Electric energy can be converted into useful work, or mechanical energy, by machines called electric motors. Electric motors work due to electromagnetic interactions: the i ...
Magnetic fields are invisible. You can’t see them, but you can see what they do, like attract a paper clip or push another magnet away. But wouldn’t it be cool if we could find out how to show the dir ...
Have you ever seen one of those roller coasters that shoots out of the station at an insanely high speed? These roller coasters don’t need to climb hills first to use gravitational potential energy—th ...

The interactions between current, the flow of electrons, and magnets can be used to do useful work, like power motors, and will continue to be important in the future because they can be used for thin ...
Hans Christian Oersted was a Danish scientist who explored the relationship between electric current and magnetism. Current is the flow of electrons, and is how we hardness electricity. Currents creat ...
Electric energy is carried by current, which is the flow of electrons, which are the negatively charged sub-particles of atoms. This transfer of electrons from one place to another powers our lights, ...
Superconductors are that conduct electric current with no resistance. Electrical resistance is the property of a material to oppose current passing through and is found in nearly everything from ligh ...
