Hi

I understand that this is a very complex topic but we will try to keep it simple and uncomplicated! Thanks.

It is said that electrons in themselves are the reason for magnetism. As is explained in the linked page that if an electron is moving CW if viewed from the top, then electron's top is North and bottom is South.

Linked page: **broken link removed**

I have a couple of questions to ask but asking them in steps would be a wise choice. In the first place I don't understand how we get circular magnetic field lines around a conducting wire. I understand that when DC current is flowing through a conductor electrons are continuous moving in one direction. But how do their collective movement create circular field lines?

This is how electron's magnetic field looks:

Could you please refer me to some diagram etc. which shows how electrons' magnetic field sums up to give circular lines, or explain it yourself?

Thank you for your help.

Consider conductor carrying current. In a plane perpendicular to the line of the conductor if one takes points at equal distances, the force is same and when these points are joined, as they are equi-spaced from the conductor result in circles.
