Forceless Magnetic Flux

[vineet_kiran]

In a container full of water,  the water molecules will be moving in all directions as described by 'brownian motion'.   But do you observe any mass flow in water filled in container?   For an observer the water in container is stationary.  Only when you heat the water to some extent you will observe convection currents moving from bottom to top showing mass flow.

That is a very interesting observation.   The brownian motion of water molecules in all directions cancell off with one another and movement of water as a whole will be zero inside the container keeping the water stationary inside the container.

By some method if you make the brownian motion of all molecules to happen in one direction,  will not the water as a whole move in that direction without taking any energy from external source?

Yes...  it will.  Have a look at the following wiki page.   I think it is the only way to do it !!

That's funny!  Doing 'work'  by the 'Grace of Ghost' is not adviceable.

In liquids and gases molecules will be moving in all directions by brownian motion.  But in solids  molecules will be vibrating in all directions with zero net effect on the total mass.

A sudden strong force or impulse on a solid mass can cause all vibrating molecules to align in one direction for a fraction of time which causes physical motion in the direction of impulse.  This is what makes motion under impulse different from normal motion under normal force.  Energy developed under impulse need not be conservative since it has additional advantage of vibrating molecules.

Same thing may happen in mechanical resonance also.
