Principle

Transformers represent a significant application of induction.
They are predominately used to transmit electrical energy over long
distances with as little loss as possible, or to adjust fixed
supply voltages to the rated voltages of electrical appliances and
equipment.
The students know that an induction voltage can also be generated
without movement of the field and induction coils relatively to
each other, because it only requires that the induction coil
contains a part of a changing magnetic field. They will therefore
understand the working principle of a transformer without any great
difficulty.

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 a given alternating voltage be increased or reduced?

Set up a model of a transformer, use it to increase and
reduce given alternating voltages and examine which conformity to
law is given.
