MAGNETIC FIELD PATTERN DUE TO STRAIGHT CURRENT-CARRYING CONDUCTOR
The region around a magnet where magnetism acts is represented by the magnetic field.
The force of magnetism is due to moving charge or some magnetic material.
Like stationary charges produce an electric field proportional to the magnitude of charge, moving charges produce magnetic fields proportional to the current. In other words, a current carrying conductor produces a magnetic field around it. The sub-atomic particles in the conductor like the electrons moving in atomic orbitals are responsible for the production of magnetic field.
The magnetic field lines around a straight conductor (straight wire) carrying current are concentric circle whose centres lie on the wire.
