Question

defined biot-savart law? find expression for magnetic of a long straight conductor by using biot-savart law?​

Answer 1

Answer:

• The Biot-Savart law starts with the following equation: →B=μ04π∫wireId→l׈rr2. B=μ04π∫wireIrdθr2. The current and radius can be pulled out of the integral because they are the same regardless of where we are on the path

Answer 2

A statement in electromagnetism: the magnetic intensity at any point due to a steady current in an infinitely long straight wire is directly proportional to the current and inversely proportional to the distance from point to wire — compare ampere's law.
