Whereas the heating and lighting effects of electric current are
directly perceivable with human senses, this is not the case with
the chemical and magnetic effects.
In this experiment, the students should recognise that a
current-carrying conductor is surrounded by a magnetic field. They
will then be in a position to understand the functioning of common
electrical appliances and equipment, such as electric bells and
For the explanation of the phenomena which occur during the
experiment, it is helpful when the knowledge of the students on
permanent magnetism (forces between magnets; magnetic poles;
magnetic fields) is refreshed prior to this experiment.
- 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
Does electric current also exert magnetic effects?
- Use a compass needle to examine whether a straight
conductor which is carrying current exerts a magnetic effect.
- Demonstrate that a coil which carries current acts like a bar
magnet, and examine on what the strength of its magnetic field is
