Question

Write down the difference between Coulomb’s Law and Biot-Savart Law

Answer 1

S. No.	Electric field	Magnetic field
1.	Produced by a scalar source  i.e., and electric charge q	Produced by a vector source i.e., current element I \(\vec {dl}\)
2.	It si  directed along the position vector joining the source and the point at which the field is calculated	it is directed perpendicular to the position vector \(\vec r\)and the current element I \(\vec{dl}\)
3.	Does not depend on angle	Depends on the angle between the position vector \(\hat r\) and the current I \(\vec{dl}\)
