The first electric alternator

Sia, who was working on some experiments, could not stop repeating the table of elements in her mind.

So when Einar entered the lab with little Daven, Sia was quite happy.

"Teacher, I am glad you have come I have some questions about the elements and their atomic weight knows how we can weigh them."

Einar sighed and smiled casually "We don't have the right tools to do it, because we would need a lot of time to develop them.

But we can do other things even more interesting. Today we will make a small crank electric generator, with which we can make electricity, which is a direct current.

For this we are going to use two magnets made of magnetite covered with copper, copper wire, a copper disk and a small support to attach a crank.

When we have the electric power generator, we will make an electrolytic bath, with which we can create a plated layer on objects to be able to protect the metals.
