Define magnetic field. give its unit. state any four characteristics of magnetic field lines.
A magnetic field is a force field that is created by moving electric charges (electric currents) and magnetic dipoles, and exerts a force on other nearby moving charges and magnetic dipoles. At any given point, it has a direction and a magnitude (or strength), so it is represented by a vector field. The term is used for two distinct but closely related fields denoted by the symbols B and H, where, in the International System of Units, H is measured in units of amperes per meter and B is measured in teslas or newtons per meter per ampere. H is a field introduced to account for the effects of magnetization, which is due to the presence of magnetic dipoles in materials. In a vacuum, B and H are the same aside from units; but in a material with a magnetization (denoted by the vector M), B/ {\displaystyle \mu _{0}} \mu _{0} is equal to the sum of H and M.
Magnetic fields are produced by moving electric charges and the intrinsic magnetic moments of elementary particles associated with a fundamental quantum property, their spin.[1][2] Magnetic fields and electric fields are interrelated, and are both components of the electromagnetic force, one of the four fundamental forces of nature.

Hey!!
magnetic fields are the fields which is created by moving electric charge in magnet.
*it's SI unit is Tesla.
it's characteristics are as follow:
* magnetic field lines never intersect each other.
*they always cover curve path.
*magnetic field lines are imaginary lines.
*magnetic field lines are closer together in the region where magnetic fields is strong.
I hope it will helps u......
