Magnetics: Exploring the Basics and Beyond

[Questioner...]

Hello,
I've come to terms that I am fascinated with magnets and how they work. I thought I would come here to ask some questions before I go out start a search on my own.

What I know:
A magnet is a medal:), It does not attract objects that are not medal. The Earth's core is basically a giant magnet.
-I know it's a lot of information to cope with.

Questions-
How does a basic atom of a magnet look like? Could we increase the number of electrons to increase the power of the magnetic field? Could Earth's iron core be the possible source of gravity being a giant magnet- seeing that we ourselves and nearly every object held to the Earth consists of small amount of iron? Could a Huge source of magnetic power attract such small amount of iron and such?

How about reading wikipedia at http://en.wikipedia.org/wiki/Magnetism

you can answer your own questions from explanations providedthere...and many others...

Magnetism is a vast subject with many interesting and strange alleys for investigation... including electron spins...and electricity...

Why are some materials magnetic and others not magnetic? You can deduce that from the wikipedia article and it may be described there as well...

Hello! It's great to hear that you are interested in magnets and their workings. I am happy to help answer your questions.

To start, let's clarify a few things about magnets. A magnet is not a medal, but rather a material that has a magnetic field. This field is created by the alignment of electrons within the material. When these electrons are aligned, they create a magnetic force that can attract or repel other magnets or magnetic materials. The Earth's core is made up of a combination of iron, nickel, and other elements, which creates a magnetic field that extends beyond the surface of the Earth.

Now, to answer your first question about the basic atom of a magnet - it looks like any other atom with a nucleus of protons and neutrons, surrounded by electrons. However, in a magnet, the electrons are arranged in a way that creates a magnetic field.

As for increasing the power of a magnetic field by increasing the number of electrons, this is not necessarily the case. The strength of a magnet depends on the material it is made of and how the electrons are aligned within that material. Adding more electrons may change the strength of the magnetic field, but it is not a direct correlation.

Regarding your question about the Earth's core being the source of gravity, this is a topic that is still being studied and researched. While the Earth's magnetic field does play a role in the overall gravitational pull, it is not the sole source of gravity. Gravity is a fundamental force that is still not fully understood, but it is believed to be caused by the mass of an object.

Lastly, magnets can attract very small amounts of iron or other magnetic materials because the magnetic field they create extends beyond the surface of the magnet. This means that even small amounts of iron can be affected by the magnetic force.

I hope this helps answer your questions and sparks further interest in the world of magnetics. Keep exploring and learning!
