called the permeability of free space:

The Biot–Savart Law

The right-hand rule for determining the direction of the magnetic field surrounding a long, straight wire carrying a current. Note that the magnetic field lines form circles around the wire.

TheMagnetic Force Between

Two Parallel Conductors

Parallel conductors carrying currents in the same direction attract each other, and parallel conductors carrying currents in opposite directions repel each other.
