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.
What magnet is made by electric currents?
All electric currents create magnetic fields. If you wind wire into a coil and pass current through the wire, that is an electromagnet.
Can electrical currents in a circuit produce thermal energy light sound and magnetic forces?
Yes to all. -- Electrical current in a toaster produces thermal energy, often known as "heat". -- In a light bulb produces light. -- In the wires dangling from eaqr-buds produces sound. -- In a solenoid coil or motor stator produces magnetic forces.
Are all magnetic fields the same size?
No
What are all the sources of magnetic fields?
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.
How are electricity static electricity and magnetism related?
well in simple terms a static electricity is charge, which is a basic quality of matter , in fact it is as basic as mass. Now, a charge in motion is a current or in other words electricity. And magnetism is a result of the motion of charge. so in a way these all three are related.
Do the other planets have magnetic fields?
yes all the other planets have magnetic fields except venus because it rotates to slowly
Do electric and magnetic lines of force physically exist?
The "lines" of latitude, longitude, reasoning, electric fields, and magnetic fields are imaginary.
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.
Can all force fields attract and repel?
No, not all force fields can attract and repel. Some force fields, like magnetic fields, can both attract and repel objects with opposite magnetic polarity, while others, like gravitational fields, only attract objects and cannot repel them.
Which planets do have a magnetic field?
Neptune, Uranus, Saturn, Jupiter, and Earth all have magnetic fields. Mercury has a very weak magnetic field.
Can a magnetic field pass through rubber?
Yes, magnetic fields can pass through rubber materials as long as the rubber is not a magnetic material itself. Rubber is typically a non-magnetic material and does not significantly affect the passage of magnetic fields.
