Here is ua answer:

Charges that aren't moving produce
electric fields.

But when those charges do move, they instead create magnetic fields. ...

The Biot-Savart Law is an equation that describes the magnetic field created by a current-carrying wire,
and allows you to calculate its strength
at various points.
