Losing Freedom to Generate Force
If an electron is alone in space, it has full freedom.
Accordingly, its spin can take any direction at any moment. Over time, the spin has an equal possibility to any directions, without showing any fixed magnetic direction.
If a spate of electrons are on a wire, they never form any effective magnetic field, since each of electrons can emit its magnetic force to any direction randomly. As a result, they equally negate magnetic force generated by others.
But, if one electron in space moves to one direction, it loses at least one element of its freedom. Or as it is engaged in one task of moving, it has to lose some of its freedom.
If a spate of electrons receive voltage to flow in the wire in one direction, they also lose some freedom. Each of them has to give up liberty to emit its magnetic force to any direction freely. Now they are bound to emit their magnetic force to one direction, thus generating magnetic force as if they were collaborating to generate a magnetic field around the wire.
Therefore, if a magnet is put closer to the wire, its magnetic field and the wire's interact with each other. Then, if the magnet is held fast by the hand, the wire put loosely would move to a specified direction according to Fleming's law.

It is very interesting that electrons flowing in a wire have one common direction of their spins to generate a steady magnetic field around the wire. But when no voltage is applied to the wire and electrons are free in orienting directions of their spins, they cannot generate a magnetic field holistically, since a small magnetic field each electron generates is negated by others or can have any direction randomly.
The issue at point is that even an electron has to sacrifice some of its freedom to do a meaningful movement whether alone or as part of a mass of electrons.
When you are alone, you are completely free. But if you work, you have to sacrifice some of your freedom.
When Christ Jesus is alone, He is completely free. But if He does any meaningful work in this world, He has to sacrifice some of His freedom.
Or as Christ Jesus gave up some of His freedom, He could have power to influence people.
And for an electron(s) to have a steady magnetic field, it has (they have) to give up its freedom in space but has (have) to move to one direction steadily.
