Electrifying and magnetizing Europe
2
Atom model By Niels Bohr
3
An electric current Alessandro Volta
4
Electrostatic force Coulomb’s law
5
A closed circuit is needed
‘voltage’ gives an idea of how much pushing force an electric field has.
6
Connection between electricity and magnetism
Hans Christian Ørsted
7
When a current flows through a wire, a magnetic field forms around that wire
Andre-Marie Ampere
8
When the wire is coiled it will give an aligned magnetic field
9
Practical use of a coil magnet
10
Electromagnetic rotation
Repelling between a permanent and an electromagnetic coil can be used to make an electromotor. Michael Faraday
11
Two electromagnetic coils make a rotor
Ányos Jedlik
