Magnetic Field of a Long Straight Wire
... At a fixed distance r from the wire, the magnitude of the magnetic field is constant (but the vector magnetic field is not uniform). The magnetic field direction is always tangent to the imaginary circles drawn around the wire, and perpendicular to the radius “connecting” the wire and the point wher ...
