Question

What is the difference between magnetic field , magnetic lines , magnetic field lines,and field lines

Answer 1

A moving charge always has both a magnetic and an electric field, and that’s precisely the reason why they are associated with each other. They are two different fields with nearly the same characteristics. Therefore, they are inter-related in a field called the electromagnetic field. In this field, the electric field and the magnetic field move at right angles to each other. However, they are not dependant on each other. They may also exist independently. Without the electric field, the magnetic field exists in permanent magnets and electric fields exist in the form of static electricity, in absence of the magnetic fieldThe area around a magnet within which magnetic force is exerted, is called a magnetic field. It is produced by moving electric charges. The presence and strength of a magnetic field is denoted by “magnetic flux lines”. The direction of the magnetic field is also indicated by these lines. The closer the lines, the stronger the magnetic field and vice versa. When iron particles are placed over a magnet, the flux lines can be clearly seen. Magnetic fields also generate power in particles which come in contact with it. Electric fields are generated around particles that bear electric charge. Positive charges are drawn towards it, while negative charges are repelled.

Answer 2

${\underline{\huge{\mathbf{\color{pink}{Magnetic\:field}}}}}$

The space around a magnet in which the needle of a compass rests in a direction other than the geographic north-south direction , is called the magnetic field of the magnet.

Extra information :-

As the distance of a point from the magnet increases , the effect of its magnetic field decreases

Magnetic field is a vector quantity .
