would activating a large electromagnet create an EMP?

or if you just turned it on and off quickly would that be an EMP?

Edited February 2, 2011 by dragonstar57

[Mr Skeptic]

Sure, and your cell phone will create EMPs and use them to communicate. However when people talk about EMPs they usually mean ones powerful enough to fry electronics. An electromagnet really isn't going to do that.

well i had an idea to try to build a electromagnet and i was woried that it might disrupt nearby electronics (would it damage anything at close range?

such as >5 feet)

and how would you make an electromagnet big enough to pick up small metal components from 8-10 yards?

how close close can an electronic device be before it is

damaged by a magnetic field of this strength?

how do you find out how much memory is used/free/total on your computer? (using windows xp)

RAM memory should be under the ctrl-alt-del Task Manager, under the "processes" tab (and then look at the bottom right corner for the total).

Harddisk memory you can find by right-clicking on the harddisk icon (in "My Computer"), and choosing properties at the bottom.

For the total harddisk memory of all disks combined, you have to add up all the harddisks and partitions manually.

would covering the walls of a room with reflective crystals create any odd optical effects?

Depends on whether you consider a potentially huge number of reflections and refractions an odd optical effect.

i consider the walls shimmering with various colors of refracted light an odd optical effect

what happens when salt and bleach is mixed

can you poor bleach in you're water softener to clean out the lines?

[Mr Skeptic]

I think you just get salty bleach.

 

can you poor bleach in you're water softener to clean out the lines?

 

I doubt it would help much, unless you are concerned about its color or possible bacteria.

the salt is crystallizing and making it so the softener is not working very well

[Mr Skeptic]

Plain water will dissolve the salt crystals. Is that what you want?

[dragonstar57]

it is forming some kind of "salt brick"

There may be a polarizing effect related, the xenon type bulb uses more power, more luminosity.

I have a quick question. Can brainwaves affect the brain? I know we have sensors which can detect brainwaves that originate in the brain, but is it possible to synthetically produce that kind of wave and send it to the brain to be perceived? That way, brain computer interfaces could be two-way and facilitate true virtual reality. If anyone knows of any research in that area please post a link.
