The magnetic field around a current-carrying wire is a fascinating phenomenon with important applications in electromagnetism.
Shape and Direction:
Imagine holding the wire in your right hand with your thumb pointing in the direction of the current flow. Curl your fingers around the wire. The direction your fingers point indicates the direction of the magnetic field lines, which form concentric circles around the wire. These circles lie in a plane perpendicular to the wire.
