physics/electromagnetism-help me with a few things plz?

Question

Okay i was in a big debate with a few people over this and i did lots of reading on wikipedia and howthingswork and coudnt find everything i was looking for

-Movement of molecules-do they make a sound when they bump past one another, and if so is the sound in a measurable frequency
-Magnets-what makes them create their field, is the field putting out any kind of frequency, and if so what wave form
-AC volts-changes at 60hz but what kind of wave is it? how does it travel through the wire. is it pulsing?
and could you provide some info on the force of earth and solar system, and force of normal everyday items on eachother

Answer 1

We hear sound due to compressions and rarefactions of some medium. If the air molecules cause compresions and rarefactions then yeas they make a sound, but it would be such a small compression that it could not be perceived by the human ear. Thank god, or else you would be driven mad by all the natural bumping of air molecules near your ear.

The fundamental reason for all magnetism is moving charges. It is not the excess or deficiency of charge it is the motion of charge. A magnets magnetism can be traced back to the spin of the electrons surrounding the nucleus of the atoms of the magnet. I am not aware of a frequency emitted by this motion.

the 60 hz wave is a translational wave (sine wave) It moves through the wire by electrons influencing each other by electrostatic repulsion ie. one electron moves and its electric field forces other electrons near it to move

the force of earth and solar system is one of the fundamental forces of nature (gravity) the other fundamental forces are electrostatic, strong nuclear and weak nuclear. The gravitational force is present between any two objects that have mass. It is proportional to the product of the masses and inversely proportional to the square of the distance between the centers of mass. This is known as Newton's Universal Law of Gravity F=G(m1)(m2)/d^2 where G is the universal gravitation constant 6.67 x 10^-11 N m^2/kg^2.

What you need is a basic course in Physics. Please take one as soon as you can. The great mysteries of the universe always look like magic to the uninformed.

Answer 2

It's not very likely that the movement of molecules make any noise. If they did, a hot dog in a microwave oven would be extremely noisy.
Magnets create a field when their electrons are aligned and the electromagnetic field surrounding the electrons are in phase and additive. No particular frequency.
AC volts at 60 Hz is a sign wave - and, yes, it pulsates at 60 Hz.
