Question

what do you mean by magnetic field write character

Answer 1

A magnetic field is a vector field that describes the magnetic influence of electrical currents and magnetized materials. In everyday life, the effects of magnetic fields are often seen in
permanent magnets, which pull on magnetic materials (such as iron ) and attract or repel other magnets. Magnetic fields surround and are created by magnetized material and by moving electric charges (electric currents) such as those used in electromagnets . Magnetic fields exert forces on nearby moving electrical charges and torques on nearby magnets. In addition, a magnetic field that varies with location exerts a force on magnetic materials. Both the strength and direction of a magnetic field varies with location. As such, it is an example of a vector field .

Answer 2

 a magnetic field is a change in energy within a volume of space.They seek the path of least resistance between opposite magnetic poles. In a single bar magnet as shown to the right, they attempt to form closed loops from pole to pole.They never cross one another.They all have the same strength.Their density decreases (they spread out) when they move from an area of higher permeability to an area of lower permeability.Their density decreases with increasing distance from the poles.They are considered to have direction as if flowing, though no actual movement occurs.They flow from the south pole to the north pole within a material and north pole to south pole in air.
