What is the magnetic flow density?
The magnetic field is called magnetic flow density or magnetic induction. It is said that the magnet has north and the South Pole; Two magnets repel each other as they point together like poles and attract when the opposite poles approach each other. Electrically charged particles are also diverted in magnetic fields.
The magnetic flow density is analogous to the features of electric and gravitational fields. The power of the electric field is the force acting on the body on the unit of charge and the force of the gravitational field is the force acting on the body per unit of weight. Magnetic fields are created by electric current. The magnetic flow density (B) is a force (F) acting on the conductive material per unit of length (L) and on the current unit (I), which can be written as equations b = f / i x L. The magnetic flow unit is called Tesla.
Magnetic field phenomenonly generated at 90 degrees to a moving electric field.The direction of electric current, magnetic field and magnetic force is defined by the rule of John Ambros Fleming's left hand. Holding the first two fingers and thumb of the left hand at right angles to each other marks the relative direction of tension, field and current. As indicated by the similarity of the first sounds of words, the thumb shows the relative direction of tension and the first finger shows the relative direction of the field. The second finger shows the relative direction of the current.
You can see a magnetic field using a mere bar magnet, a sheet of white papers and some iron submissions. This is done by placing the magnet under the paper and slightly sprinkling the paper. Filling is cured with curved lines of magnetic field flow. More submissions will be attracted at both ends of the magnet than in the middle, which means that the magnetic tokje at these points strongest. This is also the case of the Earth's magnetic field.
Earth's magnetic field is caused by the presence of molten, rotating iron in the center. Its flow density is the strongest at the north and south poles. ElectricalKycked particles from the sun are attracted by poles that cause Aurora borealis or northern lights and aurora Australis or southern lights.
Weaker magnets are cope with the lines of the flow of stronger magnets. It is this phenomenon, which is used by a compass, which is a very weak magnet. According to convention, the compass is pointed to the North Pole of the Earth, but if the compass was magnetized in the opposite direction, it would point to the South Pole.
