Question

При каком движении электрического заряда вокруг него образуется электрическое поле? магнитное поле ?

Answer 1

Электрическое поле существует вокруг заряда всегда.
Магнитное поле появляется только у заряда, который двигается с ускорением

Answer 2

Electric and Magnetic Fields

When does an electric field form around a moving electric charge?

An electric field forms around a moving electric charge. This phenomenon is described by the concept of electric fields in physics. The concept of electric fields was first introduced by Michael Faraday in the 19th century and later developed by James Clerk Maxwell in his electromagnetic theory. When an electric charge moves, it creates an electric field around it.

When does a magnetic field form around a moving electric charge?

A magnetic field forms around a moving electric charge. This phenomenon is described by the concept of magnetic fields in physics. According to the Biot-Savart law, a magnetic field is produced by the motion of electric charges. When an electric charge moves, it generates a magnetic field around it.
