Principle

Motors with a low performance are frequently constructed on the principle of an electromagnet which rotates in the magnetic field of a permanent magnet.
It can be assumed that the students already have knowledge on electromagnets, permanent magnets and the reciprocal effects between magnetic fields.
They are now to use a model of a permanent magnet - direct current motor to become acquainted with the principles of the construction and the functioning of an electric motor.

Benefits

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

Tasks

How does an electric motor function?

Place a permanent magnet on the model of an electric motor, and make yourself familiar with the construction and functioning of a motor.
