Electrifying and magnetizing Europe

Atom model By Niels Bohr

An electric current Alessandro Volta

Electrostatic force Coulomb’s law

A closed circuit is needed ‘voltage’ gives an idea of how much pushing force an electric field has.

Connection between electricity and magnetism Hans Christian Ørsted

When a current flows through a wire, a magnetic field forms around that wire Andre-Marie Ampere

When the wire is coiled it will give an aligned magnetic field

Practical use of a coil magnet https://www.youtube.com/watch?v=lSmuqLtmuwg

Electromagnetic rotation Repelling between a permanent and an electromagnetic coil can be used to make an electromotor. Michael Faraday

Two electromagnetic coils make a rotor Ányos Jedlik

Electromotor in a home device

Electromotors in a non-home device

The opposite: turn movement into electricity Antoine-Hippolyte Pixii

Now: experiment time! Build your own magnet Make an electromotor
