SUMMARY

This discussion centers on the fundamentals of magnetism, highlighting the nature of magnets, their atomic structure, and the relationship between Earth's iron core and magnetic fields. Participants explore the concept that a magnet is a material that attracts ferromagnetic objects, and they inquire about the atomic composition of magnets, specifically the role of electrons and electron spins. The discussion also touches on the Earth's core as a significant source of magnetic influence and its potential connection to gravity.

PREREQUISITES
  • Basic understanding of atomic structure and electron configuration
  • Familiarity with ferromagnetic materials and their properties
  • Knowledge of Earth's geological composition, particularly its iron core
  • Concepts of electron spin and its relation to magnetism
NEXT STEPS
  • Research the atomic structure of magnets, focusing on electron spins and their contribution to magnetism
  • Explore the properties of ferromagnetic materials and their applications in technology
  • Investigate the relationship between Earth's magnetic field and its core composition
  • Study the principles of electromagnetism and how electricity interacts with magnetic fields
USEFUL FOR

Students, educators, and enthusiasts in physics and earth sciences, as well as anyone interested in the principles of magnetism and its applications in technology.

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...
