the poles (north and south) create the magnetic fields Magnetic fields are, in the end, the result of the movement of electrostatic charges. Any charged particle will create a magnetic field around its path of travel. (And, conversely, it can be affected by an external magnetic field.) It could be the separation of charges that creates a magnetic dipole, as in an atom. (Positive nucleus with the negative electron cloud about it.) It could be the movement of electrons in a conductor. (Electric current flow in a wire.) One of the four basic forces in the universe is the electromagnetic force. Not the magnetic force, but the electromagnetic force. If there's no moving charge, there's no magnetic field. The two phenomenon are intrinsically connected.

Is limestone magnetic?
No, the limestone is not magnetic due to the magnetic fields in the stone itself.
Do humans have a magnetic field?
No. The magnetic fields of objects such as planets are due to currents withing their molten interiors. Asteroids are completely solid and so do not have magnetic fields.
Creates a magnetic field?
Both magnetic materials and moving electric charges induce magnetic fields.
Is there an antimagnetic material that is thin and block or diverted it all magnetic flux fields?
Yes, a grain-oriented form of iron called mu-metal is used as a screen of magnetic fields for such things as CRT's. This material has a high magnetic permeability, called mu (the Greek letter) in the trade, hence mu-metal. Effectively it 'short circuits' a magnetic field. A double screened cage called a Faraday Cage does the same function for electromagnetic fields.
When the magnetic fields of two or more magnets overlap what is the results?
They will combine to make a single magnetic field.
Are all magnetic fields the same size?
No
Do the other planets have magnetic fields?
yes all the other planets have magnetic fields except venus because it rotates to slowly
Can all currents produce magnetic fields?
yes
When was The Magnetic Fields created?
The Magnetic Fields was created in 1989.
Do electric and magnetic lines of force physically exist?
The "lines" of latitude, longitude, reasoning, electric fields, and magnetic fields are imaginary.
What is a science experiment that demonstrates that magnetic fields cannot be blocked?
Magnetic fields can be blocked. Magnetic fields cannot penetrate a superconductor, and regions can be shielded from magnetic fields using ferromagnetic materials.
Which planet has a magnetic shield?
All planets have magnetic fields. I believe that in most cases, this magnetic field can act as a shield.
What do you need magnetic fields for?
magnetic fields are essential to production of electricity
What can be inferred about magnetic fields and paper?
Paper is not affected by magnetic fields.
What are the source of magnetic fields?
The source of all magnetic fields is moving electric charge: whether it is current in a wire, unpaired electrons in an atomic orbital, convection currents in the earth's liquid nickle/iron core, plasma in the sun, etc. moving electric charge is the source of all magnetic fields.
Which planets do have a magnetic field?
Neptune, Uranus, Saturn, Jupiter, and Earth all have magnetic fields. Mercury has a very weak magnetic field.
How Rocks that have magnetic fields that point south?
rocks with magnetic fields that point south have
