1 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

12 Electromotor in a home device

13 Electromotors in a non-home device

14 The opposite: turn movement into electricity
Antoine-Hippolyte Pixii

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