:
the portion of space near a magnetic body or a current-carrying body
in which the magnetic forces due to the body or current can be detected.
What is a magnetic field one word answer?
The definition of a magnetic field is
a place in space near a magnet or an electric current
where a physical field is created from a moving electric charge that creates force on another moving electric charge. An example of a magnetic field is the Earth’s magnetic field.
What is magnetic field short answer?
The magnetic field is
the area around a magnet in which there is magnetic force
. Moving electric charges can make magnetic fields. … The closer the flux lines are to each other, the stronger the magnet is. The farther away they are, the weaker. The flux lines can be seen by placing iron filings over a magnet.
How magnetic field is created?
Conversely, a magnetic field is
produced by an electric charge in motion
. This is in accordance with Faraday’s Law of Induction, which is the basis for electromagnets, electric motors and generators. A charge moving in a straight line, as through a straight wire, generates a magnetic field that spirals around the wire.
What exactly is a magnetic field?
The magnetic field is
the area around a magnet that has magnetic force
. All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. … The piece of iron has become a magnet. Some substances can be magnetized by an electric current.
What is the best definition of a magnetic field?
:
the portion of space near a magnetic body or a current-carrying body in which the magnetic forces due to the body or current can be detected
.
What is an example of a magnetic field?
Examples of magnetic force is
a compass, a motor
, the magnets that hold stuff on the refrigerator, train tracks, and new roller coasters. All moving charges give rise to a magnetic field and the charges that move through its regions, experience a force.
What do you mean by magnetic field Class 6?
The magnetic field is
a region or space where there is an influence of a magnet
. … Bar magnets, rod magnets, horseshoe magnet, ring magnet etc. All types of magnets have two poles; North Pole which is indicated by ‘N’ and South Pole which is indicated by ‘S’. Irrespective of shape every magnet has a field around it.
Can you see a magnetic field?
Magnetic fields are everywhere–
you just can’t see them*
. … Usually, that’s earth’s (relatively weak) magnetic field. But they also can be used to probe the field structure around stronger magnets, as they align to the sum total field at any given location. Compasses are easy to make.
Do magnetic fields exist?
However,
purely magnetic fields do exist
. Therefore, magnetic fields are more than just relativistic electric fields. The correct statement is that electric fields and magnetic fields are both fundamental, both are real, and both are part of one unified entity: the electromagnetic field.
Why magnetic field is produced?
A magnetic field describes a volume of space where there is a change in energy. As Ampere suggested, a magnetic field is produced
whenever an electrical charge is in motion
. The spinning and orbiting of the nucleus of an atom produces a magnetic field as does electrical current flowing through a wire.
Are humans electromagnetic?
The human is
a electromagnetic field
or is like a electron that come form the electromagnetic field . the photon is a electron magnetic field and it generates the electron and positron. The photon may also be a resultant of an electromagnetic field .
Why do magnetic fields repel?
If you hold two magnets the wrong way around, they push apart
– they repel! … When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. So the magnets will push apart (repel).
What is the symbol for magnetic field?
| SI electromagnetism units v t e | Symbol Name of quantity Symbol | B magnetic flux density, magnetic induction T | Φ, Φ M , Φ B magnetic flux Wb | H magnetic field strength A/m |
|---|
Where is a magnetic field strongest?
The magnetic field is strongest at
the poles
, where the field lines are most concentrated. Field lines also show what happens to the magnetic fields of two magnets during attraction or repulsion.
Are magnetic fields harmful to humans?
At low frequencies, external electric and magnetic fields induce small circulating currents within the body. … Despite extensive research, to date there is no evidence to conclude that
exposure to low level electromagnetic fields is harmful to human health
.
