1. Spontaneous magnetization to the rescue of induction in electrical engineering

It can't be said often enough that without abundant materials with broad, spontaneous magnetization (J s ), electrical engineering would no doubt have been sorely missed on earth... or at least would have become very cumbersome!

In fact, magnetic flux f is the magnetic magnitude for understanding the operation and sizing of any electrotechnical device. We have already seen that :

ϕ=BS

and

B=μ0
