what is biot savart law?
Answers
Answer: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. ... And we also replace the electric field E with a magnetic field element dB because a moving charge produces a magnetic field, not an electric field.
Please mark it the brainliest answer if it helps you.
Answer:
Consider a very small element of length dl of a conductor carrying current (i). Magnetic induction due to small element at a point P distance r from the element.
Magnetic induction(dB) is directly proportional to
i) current
ii) length of the element (dl)
iii) sine angle between r and dl
iv) inversely proportional to the square of the distance from small element to point P
