Principle

Variously constructed relays are frequently used in circuitry, e.g. to open or close very distant elctric circuits or such which are difficult to access.
In this experiment the students should learn to understand the working principle of an electromagnetic relay.

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

How can electromagnets be used to carry out switching functions?

Close and open a circuit by means of an electromagnetic switch.
