the greater the voltage produced. Faraday also observed that it was more efficient if the coil was wound around a metal core, as this helped to concentrate the magnetic field.
The induced voltage produces an induced current ... For example, if a magnet is moved into a coil of wire, the induced magnetic field tends to repel the magnet back out of the coil.
Learn how microphones and amplifiers work together to convert sound to electrical signals for clear audio output.
Getting a magnetic field to balance on another magnetic field ... He pulled off this tricky project using a set of four coils he got off of Taobao (the Chinese version of eBay), a hall effect ...
