A moving charge produces :

The correct answer is Option (3) → magnetic field and electric field both

Every charge, at rest or moving, sets up an electric field around it (Coulomb's law). When the charge moves, it also sets up a magnetic field, given for a slow charge by the Biot-Savart law in the form

    \( \displaystyle \vec{B} = \frac{\mu_0}{4\pi}\,\frac{q\,\vec{v}\times\hat{r}}{r^{2}} \)

So a moving charge produces both fields, while a charge at rest produces only an electric field.

Option (1) magnetic field only — Incorrect. The electric field of a charge does not disappear when it moves; a charge always has an electric field.

Option (2) electric field only — Incorrect. An electric field alone belongs to a charge at rest; motion adds a magnetic field.

Option (3) magnetic field and electric field both — Correct. The charge gives an electric field because it is charged and a magnetic field because it moves.

Option (4) neither electric field nor magnetic field — Incorrect. A charge always produces at least an electric field, so "neither" is impossible.

NCERT (2026-27):
Sources and Fields – “… Just as static charges produce an electric field, the currents or moving charges produce (in addition) a magnetic field, denoted by B (r), again a vector field.”
