How to turn your smartphone into a temporary magnet
In short: Discover how Michael Faraday's principles of static magnetism allow you to transform a standard battery into a magnet by simply rubbing it against fabric.
This experiment explores the concept of static magnetism, a discovery made by Michael Faraday that links electricity and magnetism into a single scheme of forces. By rubbing a battery—particularly effective with lithium-ion phone batteries—in a north-south direction against a non-conductive surface like jeans or a jumper, you initiate an electron transfer.
This movement drives electrons toward the positive terminal, forcing them to align on a single plane. This alignment combines the individual magnetic dipole moments of the electrons, creating a much larger magnet. This phenomenon is part of a broader field of magnetic theory that includes ferromagnetism, paramagnetism, and electromagnetism, all of which are essential to modern technological industries.
