The direction of the magnetic field lines around a straight conductor depends on the direction of the current flowing through it.
The direction of the magnetic field around a straight conductor is determined by the direction of the electric current flowing through it. According to the right-hand grip rule, if you imagine grasping the conductor with your right hand such that your thumb points in the direction of the current, your curled fingers will represent the direction of the magnetic field around the conductor. This relationship is described by Ampere’s Circuital Law. The direction of the magnetic field is a crucial aspect in understanding the interaction between current-carrying conductors and the principles of electromagnetism in electrical systems.
