![]() The applications of Biot Savart Law are mentioned below. The biot savart law formula can be given as It is inversely proportional to the square of the distance of the given point from the current element r. ![]() This flux density dB is proportional to the length of the current I, element dl, the sine of angle θ between the direction of the current and the vector joining a given point of a magnetic field and the current element. The mathematical expression was derived through observation and calculations, which showed the magnetic flux density. ![]() Witnessing the deflection of the magnetic compass needle, these scientists concluded that the current particle projects a magnetic field into the space surrounding it. In 1820 two French physicists Jean Baptiste Biot and Felix Savart created the Biot Savart Law statement, which derived the mathematical formula for magnetic flux density at a point due to a nearby current-carrying conductor. As Coulomb's law is fundamental for electrostatics, similarly, Biot Savart Law is also fundamental for magnetostatics. ![]() Also, this law is consistent with both Gauss's theorem and Ampere's circuital law. According to this law, the magnitude, length, direction, and proximity of the electric current is related to the magnetic field. The magnetic field created by a constant electric field is described by the Biot Savart Law equation.
