Static Cling?
« on: 12/06/2012 05:50:26 »
I've seen this throughout Science Fiction shows.

The question i want to ask is, "Is it possible to charge someone's say hand to a brick wall through static charges?"

If so, how long will it last and how is it done?

And if not, what's the science behind it?

I believe static electricity is a fairly weak force based on SURFACE charge, so you might be able to get a balloon to stick to a wall, but not a car tire.  It would be difficult to get adequate charge separation to get the car tire to stick.

However, electricity can cause muscles to contract.  This can be particularly problematic when grabbing a live electric wire.  The muscle contractions can be so strong that it is impossible to let go of the electric wire, and one literally holds onto it until one dies.

I believe that is the reason that all modern electric fence chargers utilize an intermittent signal.

Is it not only weak because of its charge?  If you were to put more energy into the static field, could you not charge something to cling?

Alright what about paramagnetism being used instead of static.

I believe paramagnetism is a product of electrons which line up in a field to lower their energies, and thus get sucked into the field.  So if you were able to control those electrons couldn't you stick to an object?
