- Both the electric and magnetic field depends inversely on square of distance between the source and field point.
- Both electric field and magnetic field are proportional to the source strength namely charge and current element respectively.
- Both obey superposition principle.
- According to Coulomb’s law,the electrostatic force between two point charges is directly proportional to the product of their magnitudes and inversely proportional to the square of distance between their centers.
- Charge element dq producing electric field is a scalar whereas the current element Idl is a vector quantity having direction same as that of flow of current.
- E is acting along the displacement vector whereas B acts perpendicular to l × r.
- E is not dependent of θ whereas B depends upon θ.
