Is it OK to use a vacuum cleaner right next to a computer?
Yes.
Could the
vacuum cleaner generate magnetic fields strong enough to affect the
hard drive or RAM or anything else in the computer?
Maximum damage is shop vac plugged in to same aleady overburdoned
circuit, and it may then trip a breaker or something. Which may cause a
particularly crappy and overloaded computer power supply to die.
(very unlikely) Ok so maximum damage is vacuum cleaner knocks computer
off desk, and cause an accident of the humpty dumpty nature.
The magnents inside a hard drive are so powerful, that if you put one
on the palm of your hand, and the other on the back of your hand, the
two magnents will stick together. Most technicians have no fear of a
magnetic screwdriver near a hard drive.
Ram is based on electrostatic charges, not magnetism. So no risk there.
Interference on a wireless network is possible, I suppose. But I don't
really think so.
