Does a beam of free electrons create a magnetic field like that of a wire with current flowing through?

And could you say what shape the magnetic field of one traveling electro would take?ZapperZ said:Yes. It is one way that we detect them when they pass through a section of a particle accelerator (i.e. using a device such as an ICT).

A magnetic field is a physical field that is created by moving electric charges, such as free electrons. It exerts a force on other moving charges and can be detected by its effects on those charges.
Free electrons, which are electrons that are not bound to an atom or molecule, have a property called spin. This spin creates a tiny magnetic field around the electron, and when many free electrons are moving together in the same direction, they can create a larger magnetic field.
The strength of a magnetic field from free electrons can be measured using a device called a magnetometer. This device uses the interaction between the magnetic field and a magnet or a compass needle to determine the strength and direction of the field.
The strength of a magnetic field from free electrons depends on the number of free electrons present, their velocity, and the distance between them. The strength of the field also decreases with distance from the source.
The direction of a magnetic field from free electrons is determined by the direction of the spin of the electrons. Conventionally, the direction of the magnetic field is defined as the direction in which the north pole of a compass needle would point if placed in the field.
