Four experiments on magnetic field at four Euros - Low-cost demonstrational experiments on Classical Electrodynamics for future physics teachers
2014
Abstract
The article presents four experiments from the area of magnetism: Demonstration of Ampere's law, How to use an electric transformer to transform music, Dissipation of magnetic field and Simple demonstration of a multipole expansion. The experiments use only simple and cheap instruments (ideally being the "experiments for 4 Euros") to enable future teachers to use simpler versions of selected experiments also in their future teaching at high schools.
