Magnetic field near a current-carrying straight wire

When an electric current flows through a straight wire, it creates a magnetic field around the wire. This magnetic field is known as the “magnetic field near a current-carrying straight wire.” The magnetic field is perpendicular to the wire and its direction is given by the right-hand rule. If you point your right thumb in…

Biot–Savart’s law

Biot-Savart’s law is a fundamental law in electromagnetism that describes the magnetic field produced by a steady current in a wire. It states that the magnetic field at a point in space due to a current-carrying wire is directly proportional to the current in the wire and the length of the wire segment, and inversely…
