What is magnetic fields for kids?
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.
What is a magnetic field easy Definition?
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. noun.
What are field lines for kids?
Field Lines This is thanks to a magnetic field, which is a surrounding area where magnetic forces occur. This area is made of field lines, which are invisible lines that extend from the magnet and either pull in another magnetic object or repel it.
What do magnetic fields show?
A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.
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.
How do we represent magnetic fields?
Magnetic fields may be represented by continuous lines of force or magnetic flux that emerge from north-seeking magnetic poles and enter south-seeking magnetic poles. The density of the lines indicates the magnitude of the magnetic field.
How magnetic field is created?
Scientists know that today the Earth’s magnetic field is powered by the solidification of the planet’s liquid iron core. The cooling and crystallization of the core stirs up the surrounding liquid iron, creating powerful electric currents that generate a magnetic field stretching far out into space.
What is the function of a magnetic field?
Magnetic fields force moving electrically charged particles in a circular or helical path. This force—exerted on electric currents in wires in a magnetic field—underlies the operation of electric motors. (For more information about magnetic fields, see magnetism. The use of magnetic fields to generate electric current.
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 is the purpose of a magnetic field?
What are facts about magnetic fields?
Facts about Magnetic Fields 1: the force. The permanent magnet generates force called magnetic field when it pulls the nickel, cobalt and iron. They are considered as the ferromagnetic materials. Magnetic field is important in the development of technology.
What produces a magnetic field?
Magnetic Field. Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits.
What is the magnitude of a magnetic field?
The magnitude of the magnetic field is 6.00 x 10 -6 T, which can also be written as (micro-Tesla). The direction of the magnetic field can be determined using the “right hand rule”, by pointing the thumb of your right hand in the direction of the current.
What are some examples of magnetic force?
Examples of magnetic force is a compass, a motor, the magnets that hold stuff on the refrigerator, train tracks, and new roller coasters.
