Circular Coil. A Current Carrying Wire Generates A Magnetic Field. According To Biot-Savart’S Law, The Magnetic Field At A Point Due To An Element Of A Conductor Carrying Current Is, 1.Directly Proportional To The Strength Of The Current, I 2.Directly Proportional To The Length Of The Element, Dl 3.Directly Proportional To The Sine Of The Angle θ Between The Element And The Line Joining The Element To The Point And 4.Inversely Proportional To The Square Of The Distance R Between The Element And The Point.
