One of the pieces of educational experiment apparatus used at The Fourth Higher School. This item is a Foucault current generator, and was used in electromagnetism for induced current education. When a direct current (6 volts, 12 amperes) is passed through the coil to make it a strong electromagnet, eddy currents are generated in the copper disk. These are called Foucault currents, named after their discoverer Jean Bernard Léon Foucault. When the copper disk is rotated by the handle, it gradually becomes more difficult as a braking effect occurs. The current inside the disk is detected by a galvanometer. Furthermore, Joule heating is generated in the disk, causing its temperature to rise. This item is a product of Max Kohl, a physics and chemistry instrument manufacturer founded in Chemnitz, Germany in 1876.

Established in 1989 to preserve and utilize valuable materials handed down from the predecessor school when the university campus was relocated from Kanazawa Castle Site. Former teaching materials such as beautifully shaped physics experiment apparatus and mushroom moulage specimens that allow you to observe mushrooms as they were 100 years ago are fun-to-see natural museum materials in the museum's collection. The museum also holds many archive such as timetables that show the hard work of medical students 100 years ago, as well as archaeological materials excavated within the campus.
