A current-carrying conductor - Lorentz Forcen a magnetic field

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.
