Electric charge in uniform motion does indeed produce both electric and magnetic fields.

* Electric Field: A stationary charge creates an electric field around it. This field exists even if the charge is not moving. When the charge is in uniform motion, the electric field lines become slightly distorted but the field itself still exists.

* Magnetic Field: This is where things get interesting. A moving charge creates a magnetic field. The strength of the magnetic field is directly proportional to the speed of the charge and the magnitude of the charge. A charge at rest does not produce a magnetic field.

Important Note:

* Uniform Motion: This means the charge is moving at a constant speed in a straight line. If the charge accelerates, it will produce electromagnetic radiation in addition to electric and magnetic fields.

Let me know if you'd like me to elaborate on any specific aspect of this!
