Electronics/Spintronics

Understand how electromagnetic induction works and experience a hands-on demonstration of spintronics, the leading-edge technology that makes use of the spin properties of electrons.

The light turns on as the electromagnetic induction seesaw is moved
Where there is electricity, there is magnetism

Understand in simple terms the close relationship between electricity and magnetism with Faraday’s famous laws of electromagnetic induction. You can experience electromagnetic induction, which is when electricity is generated at both ends of a coil as a magnet is moved close to it.

Einstein’s 
The one and only experiment in Einstein’s life

It was the experimental equipment used for the Einstein–de Haas effect that demonstrated the gyromagnetic effect, which is the basic principle of “spintronics,” now at the cutting edge of magnetics. This is said to be the Einstein’s only published experiment in his lifetime.

Einstein-de Haas Experimental Equipment Trial Kits
Let’s try to see the gyromagnetic effect firsthand!

You can learn in a simple and hands-on way about the gyromagnetic effect, which is the basic principle of spintronics, with two types of trial kits for the Einstein–de Haas effect and the Barnett effect respectively.

    Experimental demonstration of the Einstein–de Haas effect

    Spintronics is a technology at the leading edge of magnetics. It is based on gyromagnetic properties known as the Einstein–de Haas effect. The experimental setup used for proving the effect is illustrated in an easy-to-understand format by this exhibit.
