Biot-Savart © RHJansen dB = μ 0 ΙδΛ ρ ρ 3 dB d = 0 2 σινθ dB = 0 2 Most problems in this course share these steps in common. After these steps the solution will vary depending on the specific problem. Devised a formula to calculate the magnetic field of a moving charge / current. The × refers to the cross product of current I and distance r to the moving charge / current. This changes into sin θ , and then the distances simplify. Summing up all the elements of magnetic field will return the entire magnetic field. The constants can be moved outside the integral, and in most of the problems in this course the angle between I and r will be 90 o . B = 0 Ι δΛ 2
Biot-Savart and Long Straight Wires © RHJansen When Biot-Savart is applied to finding the magnetic field near a long straight wire the formula simplifies into the equation.
