1. field at any point vary inversely at the square of the distance.

2. both obey superposition principle

3. the magnetic fields linear in the source just as electric field.


1. E is produced by a scalar source (q) where as B is produce by vector source (Idl)

2. E is acting along the displacement vector where as B acts perpendicular to Ixr.

3. E is not depended of θ where as B depends upon θ.
