MAGNETOSTATIC FIELDS

Analogy between Electric and Magnetic fields

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.
