Professor Mori's
study of magnetics

This is a collection of episodes related to magnetic research written by Professor Mori.
In the course of research, hints are hidden about how discoveries and inventions are made.

Invention of the MI sensor

In 1993, it was discovered at Nagoya University in Japan that applying magnetism to amorphous wires significantly changes impedance, and moreover, a highly sensitive magnetic sensor was invented that applies this effect. This is the MI sensor. The special magnetic structure of the amorphous wire provides very high sensitivity.
