Study Notes

Electricity and Magnetism

Benjamin Franklin, an American scientist, studied electricity.
In the early days, electricity and magnetism were separate fields.
Later, experiments showed a connection between them.
This connection led to a new branch of study called electromagnetism.
An electroscope is a device used to detect electric charges.
A gold leaf electroscope uses the movement of a gold leaf in response to an electric charge to detect and measure an electric charge. Metal is used as the core of the electroscope.
