Principle

The students should know, that a current-carrying conductor is
surrounded by a magnetic field whose field lines are concentric
circles, and how one can determine the direction of the field
lines. They should also know the conventions, that the field lines
external to a permanent magnet or an electromagnet run from the
North pole to the South pole, and electric current flows from
the positive pole to the negative pole.
The students should find out that a force acts on a
current-carrying conductor in a magnetic field and how one can
determine its direction.

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 electric current generate mechanical movement?

Let current flow through a conductor which is in a
magnetic field, and investigate whether forces act on the
conductor and which direction these forces have.
