Magnetic field - conductor models set of 3

For demonstrating the magnetic field around current-carrying conductors of various shapes, the test result (the magnetic field lines around the respective conductor) can be projected;
The iron filings are in a viscous medium, hermetically sealed in a sealed acrylic glass cuvette. The liquid causes the filings to align themselves much better in the form of the magnetic field lines than in conventional experiments with filings on a cardboard or acrylic glass plate. The test result is therefore more meaningful and impressive. There are also no loose shavings, we enable “clean” experimentation!
3 conductors in straight, loop and coil form, embedded in temperature-resistant nylon profile;
Connection sockets for 4 mm laboratory or safety plugs;
Dimensions of the projection surfaces: 106 x 106 mm each
