A magnetic field is generated by a moving electric charge. The fundamental place where such a charge lies is on the electron. So when an electron moves (including just spinning in place), it generates a magnetic field.
A common substance will have equal numbers of clockwise and anti-clockwise spinning electrons, and there will be no net spin, and therefore no net magnetic effect. In some materials, a group of magnetic domains will aggregate, thus becoming a 'permanent magnet'. Some of these are natural materials.
And, when an electric current (a flow of electrons) moves down a conductor, it will generate a magnetic field.

If two magnets come together you say they what each other?
if two magnets come together we say they are
Why do iron filings form 3-dimensional shapes with magnets?
They are attracted to the magnets.
How do magnets differ other than shape and size?
Magnets also come in different strenghs
What is loadstone?
loadstone is the natural form of magnets.
Do magnets come from the south pole?
negative
Are magnets only made from the earth?
Yes, and no. Magnets originally come from the earth but humans found what the were made of and created their own
How do magnet s generate electricity?
Magnets are just rocks that come from the Earth. The Earth has grvaity, and when the magnets come up frm the ground they keep there gravity with them and thts how it wrks.
What are magnets come from?
most of the time a rock called magnetite.
How come magnets look plastic and are flexible e.g like some fridge magnets?
Fridge magnets are usually made of flexible vinyl with thin magnetic strips in them to make them magnetic.www.magnets.com
Is magnetism consider a form of energy?
yes magnet is energy, surprisingly. magnets have at least one north pole and south pole, which make magnets have energy. Magnets provide energy. When you have two magnets and they are pushing against each other, that is how magnets provide energy. Magnets are better for the enviornment, because magnets are pollution-free.
What are the uses of super magnets?
Super magnets are used to help produce sound in speakers. They also help pick up vibrations in electric and bass guitars. These magnets come in many different forms.
why do magnets behave in a different ways?
So that they can come together quickly
