Difference between biot savart law and coulomb's law

Answer 1

Comparison between Biot-Savart Law and Coulomb's Law: Similarities: Both magnetic and electric fields at a point are inversely proportional to the square of the distance between the field source and the point in question. ... Magnetic field due to a moving charge (Biot-Savart law) is: B = (μo/4π) × idl(sinθ)/r.
