Region where a force is produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits (such as in magnetic materials). The strength of a magnetic field is defined as the force on moving charge and is measured in the common units of Tesla (T) or Gauss (G), where 1T=10000 [..]

Region around a body in which a magnetic force is detected. Fairly weak magnetic fields are generated by dynamo effects inside planets and moons. Magnetic fields more than one billion times stronger may be generated in stars and galaxies. These are capable of controlling the motion of ionised gas and even the shape of objects.

The region within which a body or current experiences magnetic force.

When specified on our site, the surface field or magnetic field refers to the strength in Gauss. For axially magnetized discs and cylinders, it is specified on the surface of the magnet, along the cen [..]

The area in which an attractive or repelling force exists between two magnets or in association with the element iron. The Earth's magnetic field is thought to be due to the liquid iron-nickel wh [..]

The Earth's magnetic field is aligned with the north and south poles, and has reversed many times during geologic history. Sharks may use the magnetic field of the Earth for navigation purposes on migrations.

A condition in the space around a magnet or electric current in which there is a detectable magnetic force and two magnetic poles are present.

A region of space around a magnet in which objects are affected by the magnetic force.

A set of imaginary lines that indicate the direction in which a small compass needle would point if it were placed at a particular spot.

region where magnetic force exists around magnets or electric currents. magnetic pole -

A region in which a magnetic force can be detected.

Model used to describe how magnetic forces on moving charges act at a distance

A region of space that has a magnetic effect on suitable objects.

Space surrounding a magnet that experiences the force of attraction or repulsion of the magnet; a region of space that is characterized by the presence of a magnetic force (Lessons 8, 22, 24, 30)

Magnetic fields are historically described in terms of their effect on electric charges. A moving electric charge, such as an electron, will accelerate in the presence of a magnetic field, causing it [..]

A detected force that exists around a magnet or electrical field.

a physical quantity which has a definite value at each point in space. We think of the field as existing in space even though there may be no particle there to experience the force. Magnetic fields can be produced by magnets made of magnetic materials (iron in particular), by electric currents and by electric fields which change with time. The SI u [..]

An identified force that exists around a magnet or electrical field.

That area near a magnet in which its property of magnetism can be detected. It is shown by magnetic lines of force.

The area around a magnetic body or a current-carrying body in which its magnetic forces can be detected. Magnetic forces have the property of attracting iron.

invisible lines of force surrounding a magnet or a conductor with current flowing through it.

     The detectable magnetic flux issuing from a magnet or electromagnet.

a region in which magnetic forces can be observed. See "electromagnetic field," a more general field also including electric forces.

Areas of attractive or repulsive force surrounding Magnets.

Area, around a magnet, in which its magnetism is manifest.

A magnetic field is an area which is under the influence of a magnetic charge. A magnetic field, like an electric field, is due to the polar nature of electric or magnetic charges. Poles are oriented [..]

The region of "altered space" that will interact with the magnetic properties of a magnet. It is located mainly between the opposite poles of a magnet or in the energetic space about an elec [..]

The region within which a body or current experiences magnetic force.

A region of space that surrounds a moving electrical charge or a magnetic pole, in which the electrical charge or magnetic pole experiences a force that is above the electrostatic ones associated with particles at rest.
