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 else can I help you with?
The strength of electric and magnetic fields remains constant as you move away from the source of the electric and magnetic fields?
yes
What does magnetic fields pick up?
Magnetic fields can pick up ferromagnetic materials, such as iron, nickel, and cobalt, causing them to become magnetized or attracted to the source of the magnetic field. They can also influence the motion of charged particles, such as electrons, which can create electrical currents. Additionally, magnetic fields are capable of interacting with other magnetic fields, allowing for phenomena such as magnetic induction and resonance.
How does distance affect magnetic fields?
Distance affects magnetic fields in the sense that the strength of the magnetic field decreases as the distance from the source increases. This relationship follows an inverse square law, meaning that the magnetic field strength reduces rapidly as distance increases. As a result, the influence and impact of a magnetic field weaken with greater distance from its source.
The magnetic fields of all the atoms in a magnetic domain?
cancel each other out. Source: Me and my 7 grade Text Book
Do magnetic fields extend out infinitely?
No, magnetic fields do not extend out infinitely. They have a limited range of influence, determined by the strength of the magnetic source and the medium through which the field is propagating. Beyond a certain distance, the effects of the magnetic field become negligible.
When was The Magnetic Fields created?
The Magnetic Fields was created in 1989.
What is the region of a magnetic field?
The region around a magnet or current-carrying conductor within which the magnetic force is exerted is called the magnetic field. Magnetic fields are three-dimensional and extend infinitely in all directions from the magnetic source.
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.
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.
The field of electromagnetism was formed when Hans Christian Oersted accidentally discovered that?
electrical currents are a source of magnetic fields
Is that brain contains magnetic field?
Question is confused, but try this... The brain does generate electrical fields, and they do change, and since changing electrical fields always generate magnetic fields ... then YES. However ... the electrical fields of the brain are of very low magnitude and are relatively slow to change (as compared to any manufactured gadget), so the brains magnetic fields are weak and are considered minor The electric field is the source code for EEG's.
