Introduction to the physics of electromagnetic field spectrum and audio spectrum with drawings. What are EMF waves? How do they travel through space? Which EMF waves are harmless, which are dangerous, and why? We detect EMF with a coil. A coil is an electrical conductor in the shape of a spiral. We use electromagnetic coils in electrical engineering in applications where electric currents interact with magnetic fields in devices such as radios, electric motors, transformers, and sensor coils. An electric current is passed through the wire to generate a magnetic field.

In the workshop, we will first open an old analogue radio to uncover how a coil is connected to an electric device. Then we will build a test coil with conducting copper wire wrapped around a pencil. We will connect it to a breadboard and listen to a crackle of the electromagnetic field in electrical devices around us such as a soldering iron, laptop computer or mobile phone. Next, we will use an industrial-grade coil and solder it to a stereo audio jack (3.5 mm) that kids will connect to a loudspeaker, which they will have built one day earlier, and listen to the EMF emissions in their immediate surroundings. At the end of the workshop, we will make a performance of electromagnetic opera.

No prior knowledge is needed to attend the workshop. The workshop is free of charge. Girls welcome!

About the summer camp

Summer camp for children from 10 to 13 years of age with an emphasis on exploring contemporary sound arts and technology! Every day workshops will be held by experienced mentors and artists. They will make various sound devices and explore the diverse field of contemporary sound art. The purpose of the camp is to bring elementary students closer to the field of contemporary research arts, which in addition to a wide range of concepts such as DIY (do-it-yourself), DITO (do-it-yourself), citizen science, bio-art, also cover science, ecology, and modern technologies.

The workshop was commissioned by konS – Platform for Contemporary Investigative Art and produced by Rampa Lab and LokalPatriot.
