Principle

It is assumed that the students know that a voltage is induced in a coil, as long as the magnetic field contained by the coil changes.
When the induction process can be triggered by a permanent magnet, then this must also be possible with an electromagnet. The students should check this practically. They should thereby consolidate their knowledge, that the change in the field must not necessarily be brought about by a (mechanical) movement of the magnet and the coil relative to each other.

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 a voltage be induced by means of an electromagnet?

Determine if a voltage can be induced by an electromagnet and examine in which way this is possible.
