Superconductors have two properties.

First of all, it is a characteristic of a “complete conductor” in which the
electrical resistance of a material becomes zero.

And it is a characteristic of 'complete diamagnetic' that completely
cancels out the surrounding magnetic field.

A dream material that has both of these properties at the same time
is a 'superconductor'.

By using this, it is possible to increase the efficiency of power transmission
by reducing the electrical resistance.

In particular, nuclear fusion, which is considered the future energy technology,
