Question

why divergence is prensent in magnetic field?? not in electric field??​

Answer 1

Answer:

Explanation:

A changing magnetic field acts as a source of curling electric field. The field lines due to such a source have no beginning or end and as such contribute nothing to the divergence. Electric field lines only begin and end on charges. Only a charge density can be responsible for a non-zero electric field divergence.

A similar explanation applies to conduction and displacement currents as sources of magnetic field.
