How Is the Biot-Savart Law Derived?

Click For Summary
SUMMARY

The Biot-Savart Law is derived from experimental observations regarding the magnetic field (B) produced by electric currents in various geometries, such as straight wires and solenoids. André-Marie Ampère and Jean-Baptiste Biot utilized these experimental results to formulate a general equation that applies to all integrable geometries. The law quantitatively relates the magnetic field to the current, the distance from the current, and the angle between the current direction and the observation point.

how is the Biot Savart law derived?? From where does it come?
 
Physics news on Phys.org
Experiment shows that B depends on current,conductor geometry etc and I assume that Biot and Savart started with experimental results from geometries such as straight wires and solenoids and worked backwards to find a general equation that covers all integratable geometries.
