![]() ![]() The Biot-Savart Law is an equation that describes the magnetic field created by a current-carrying wire and allows you to calculate its strength at various points. ![]() For applications, students find it is necessary. Via a lecture, students learn Biot-Savart's law (and work some sample problems) in order to calculate, most simply, the magnetic field produced in the center of a circular current carrying loop. (iv) inversely proportional to the distance between the point and the mid-point of the conductor. Beginning with a class demo, students are prompted to consider how current generates a magnetic field, and the direction of the field that is generated. (iii) directly proportional to the sine of the angle between the lines connecting the point from the mid-point of the conductor and the conductor itself and (ii) directly proportional to the length of the conductor. (i) directly proportional to the amount of current. Law: The magnitude of magnetic field at a point produced around a conductor of small length due to the flow of current through it is. This law is applied to the generation of a magnetic field due to conductors of any shape and different current distributions. Later on, in 1820 scientists Biot and Savart gave an experimental proof of this law. To determine the magnetic induction or magnetic intensity of this magnetic field, scientist Laplace gave a theory or law. Scientist Oersted discovered that there exists a magnetic field around a wire carrying current. ![]()
