No investigation into electromagnetic theory is complete without measuring the inductance and self-inductance of a current-carrying coil (depending on the insertion of an iron core) and exploring AC circuits.

Our copper wire coil features a shock-resistant plastic casing with lifting handles, a coated iron core mounted on a worm screw for moving in and out of the coil, and a scale printed in cm for reading the length of core inserted into the coil.
