Erthalos' classroom

Welcome in my classroom.

Here, I'm going to teach you almost everything I know about vibratory phenomenons, and waves, mechanic waves, acoustic waves, and even electromagnetic waves, as far as some electromagnetic interactions with matter, and electromagnetism in the void.

Students, please put your names in the appropriate section !

These courses will mainly work in a question/answer basis, and I'll develop subject asked.

Guidelines, provided by A. Einstein

The only absolute thing in our world is humour.
Don't ever forget this.

If facts don't agree with theory, change facts.
Do it with moderation still.

Nothing is closer to Truth than False.
We're all here to learn, mistakes are allowed.

If you can't explain something to a 6 years old child, then you don't understand properly that thing
I hope I'll do it !

I want to know what God thinks. Anything else is a detail.
The aim of every physicist.

Question :

Q. Why does the electromagnetic pull of the moon control tides, weather, migration and such other things. Why is this electromagnetic pull so important? or is it something else entirely?

A. First of all, the moon doesn't have any electromagnetic field. The pull is due tu gravitation, and it only causes tides. The moon and the sun cause tides, because of the attraction they exert on the water of the oceans.
Weather control comes from the difference of heat in air masses, just because of solar energy.
Migration of some birds is helped by the terrestrial electromagnetic field. Birds are able to sens the intensity of the EM field, and also sense it's declinasion (sp?), meaning the angle it does with a horizontal line. This with checking stars enable them to locate their position and their ways with a good accuracy.
