Some
of these are:
(i)
Both are long range, since both depend inversely on the square of
distance from the source to the point of interest The principle of
superposition applies to both fields [In this connection, note that
the magnetic field is linear in the source I dl just as the electrostatic
field is linear in its source: the electric charge ]
(ii) The electrostatic field is produced by a scalar source, namely, the electric
charge
