The permanent exhibition entitled 'Electro Magica' is an adventure to the beginning of electricity. It presents the development and most important stages of electro technology.

Experiment that led to the birth of electrostatics and electrodynamics are demonstrated to the visitors by varies interactive equipments. The stories shed light on the experiments that were performed in noble salons. We activate cathode ray tubes, and the visitors can also see a nearly 100.000 voltage spark inductor from the 19th century in operation. The visitors can also see the watt meter invented by Ottó Titusz Bláthy in operation. Another Hungarian invention to see is the switch board that was used in telecommunication.

A booklet was published to accompany the exhibition. It can be really useful in primary and secondary school education. The booklet can be purchased at the museum.

The interactive exhibition offers an unforgettable experience both for children and adults.

In the 1980's several leading electro technicians dealt with one of the most exciting technological issues of the time: the division of electric power into units and its transport to far distances. Most of them stood by direct current, but the brand new system, the alternating current that was used in the Ganz Factory launched the race between a.c. and d.c. Of course, d.c won the race.

Three engineers working for Ganz Factory, Károly Zipernowsky, Miksa Déri and Ottó Titusz Bláthy solved the problem of transporting electric power to considerable distances. It is less known that it is the system these three engineers invented that is still in use across the world.

The exhibition presents the circumstances of the invention of transformer, the development of technology related to it via authentic duplicates.
