A magnetic field is created as a result of some type of uniform motions of charges. Take the electron, the basic "moving charge" we know so well. When an electron moves (or when any charge particle moves), it generates a magnetic field around its path of travel. Every time. All the time. It cannot be helped. And when electrons move in a conductor, and the conductor is wound around a ferromagnetic core, we create an electromagnetic. (The charges move in only one direction through the coil of an electromagnet.) In a permanent magnet, the ferromagnetic material is formed, and then heated and cooled, the heating and cooling done in the presence of a fixed magnetic field. That field will align magnetic domains (at the atomic level) in the wannabe magnets, and that alignment will be greatly facilitated by heating. By maintaining the static magnetic through the cooling cycle, the magnetic domains that were aligned will then have been "trapped" in position by the cooling.
Both fields are said to be made up of lines of force.
Electric fields (electrostatic fields) can exist by themselves. Magnetic fields exist solely - repeating that - solelybecause they've been created by some sort of uniform motion of charges. One of the four fundamental forces of the universe is the electromagnetic force. Not the electric force. Not the magnetic force. The electromagnetic force. The two forces are linked in the most profound and fundamental way.
An electric field is a region around a charged object where the object's electric force is exerted on other charged objects.
The word magnetic field is a noun. It means a region which is near or around a magnetic material.

What is another word for earths magnetic field?
= An effect of the magnetic field is "Van Allen radiation belt" =
What does the word polar mean?
Polar refers to the north and south poles. The poles are also the centers of the magnetic field that is around the Earth.
What is field specific vocabulary?
Field specific vocabulary refers to the diction that is specific to a certain field. Professionals in these fields use these types of words, so unless someone is in that field or are well acquainted with it, they may not understand these words. An example is the scientific medical terms used to define diseases, anatomy, symptoms, and more in medicine.
Do you use magnetic metals in everyday life?
There are two types of magnetic metals, those that are permanently magnetic, and those that become magnetic as a result of an electrical field, i.e. electro-magnets. * Some games such as travel chess have small magnets in the bases of the pieces, to hold them to the metal board. * Cupboard 'catches' can be magnetic. They close on contact, but can easily be released by pulling the door. * Some necklaces have a magnetic fastener. * Magnets are used to pick up magnetic items such as staples, paper clips, pins, * Small magnetic blocks are used to store paper clips on a desk. * Credit and ATM/cash cards have a magnetic strip on one side. It is magnetic because it contains magnetic metal powder in the plastic * Some screwdrivers are magnetized, to hold the screw prior to screwing the screw into wood or other material. * Cathode ray televisions and computer monitors use an electromagnet to direct electrons/pictures to the screen. * VHS tapes and common audio cassettes use magnetic tape, a thin plastic strip coated with a thin layer of magnetic powder in film form. * In computers, floppy disks and hard disks record data on a thin magnetic coating. * Speakers and Microphones have permanent magnets as part of their construction. * Electric motors and generators have combinations of electromagnets and permanent magnets * Refrigerator magnets use magnetic metal to make them stick to the refrigerator. * A manual compass uses a magnetized needle to indicate magnetic North.
Define the term radiation exposure?
In the field of physics related to health, the term radiation exposure refers to people being exposed to radiation either through laboratory testing or in treatment of diseases.
How do scientist know that magnetic field originate from north always?
There are two kinds of magnetic poles. It is just a matter of convention that we *define* one of the north. Then we *define* the direction of the magnetic field to be the direction of force experienced by a test north pole. Magnetic field lines and their directions don't really exist, they can only be observed indirectly. It follows from our definition that they must originate in the north poles.
Define permanant magnet?
(n.) a magnet that retains its magnetism after being removed from an external magnetic field
The area around an object that is affected by the magnetism of that object is the?
A Magnetic Force
Region around a magnet in which magnetic force can act?
Magnetic freild
Does Eris have a magnetic field?
no. Eris does not have a magnetic field
What is a region where a magnetic force can be detected?
The magnetic field. If it's an electromagnet, the electromagnetic field.
What is the neutral point of the magnetic field?
In a combined magnetic field, a neutral point is a place where the magnetic field is zero
Can things hover in a magnetic field?
Things that are affected by a magnetic field, such as iron and steel can hover in a magnetic field.
What is a magnetic field made up of?
Magnetic field is made up of magnetic lines.
What is a magnetic field will be produced at some point in space if the electric field at the point?
As far as the electric field is stationary then no magnetic field. But when electric field is moving at a uniform speed then a magnetic field will be produced. This is what we call Lorentz magnetic field.
Does Ceres have a magnetic field?
No, Ceres does not have a magnetic field around it.
What is the magnetic character for iron?
the answer is the iron of magnetic field so that it can cause magnetic field... iron.
