Generation of an induced voltage with permanent magnets

Principle

The students know that a current-carrying conductor is surrounded by a magnetic field which can cause mechanical movement in interaction with another magnetic field. They should demonstrate the reversal of this phenomenon, i.e. demonstrate that electrical energy can be generated by mechanical movement. They should come to the realisation, that a voltage is only induced, when the magnetic field which is contained by a coil (or conductor loop) changes.

Benefits

• No additional cable connections between the building blocks needed - clear arragned and quick setup
• Contact saftey due to puzzle blocks system
• Corrosion-free gold plated contacts
• Doubled earning sucess: Electric circuit diagram on top, real components can be seen unterside

Tasks

Can an electric potential be generated by moving a conductor or a permanent magnet?

Investigate if the process in which a current-carrying conductor is deflected in a magnetic field, i.e. in which electrical energy is converted into mechanical energy, is reversible.
