This document discusses magnetostatic fields and laws governing magnetic fields produced by electric currents, including Biot-Savart's law stating that the magnetic field produced by a current element is proportional to the current and inversely proportional to the distance from the element. It also covers Ampere's circuit law relating magnetic fields to their sources, applications of this law to infinite line and sheet currents, magnetic flux density as defined by Maxwell's equations, and magnetic forces.

- 3. Biot-Savart’s Law • Biot-Savart’s law states that the magnetic field intensity dH produced at a point P, by the differential current element Idl is proportional to the product Idl and the sine of the angle α between the element and the line joining P to the element and is inversely proportional to the square of the distance R between P and the element.
