do magnets affect gadgets like watch ,speedometre

[dodo319]

Well most of the time cause like if you put a magnet on the computer screen when it's on you will see something happen, if you a magnet on some gadgets it will take the gadgets power

Some watches yes. speedometers are quite unlikely as they are mechanical. Tachometers can be but it takes a rather strong one. Many electronic devices can and are affected by magnetic forces. Computers, TV, some radios, cumpases, some GPS devices and many more.

they can, for instance a CRT monitor uses two electro magnets to steer an electon beam across the screen to generate your picture...if you hold a magnet close it interferes and screws up the picture...(dont it can screw up your TV/monitorMagnets can effect other devices...relays and solenoids both are based on magnets...aditionally if the magnet it moved over an an object it can generate current. Most effects are miniscule, but if you have a large enough magnet just about anything "could" be effected, depends on the device...like an electronic speedometer yes, the needle moves by the use of magnets so a stronger field would change it's position.I've heard of watches being screwed up by strong magnetic fields as well.

A lot of that depends on the gadget. But the general answer is yes. Unless you know for a fact that the 'gadget' involved isn't sensitive to magnetic fields, it's a good idea to keep magnetics away from it.Doug

[Science Guy]

Yes, it effects electronic gadgets. The polarization of the magnet messes up that of the gadget.

They do indeed, don't believe me?
Look at Magnets and Phones

Indeed, dont get a magnet near your HD either! Or a floppy disc for that matter. My girlfriend once stuck a floppy disc to the fridge with a magnet with a note saying 'here's the disc you were looking for' ... Cheers luv, but you killed it!

Hahahahahhahaha
Wickedly funny mate
It reminds me of the time my lads wench put some tinned hot dog sausages in the microwave minus brine and then wondered what the loud bang was.
But hey who'd live without `em, women I mean not hot dogs, although saying that some might disagree. :D

Someone once showed me his research NMR magnet, but asked beforehand if I had a pacemaker.

Bit extreme, but possibly counts.

Speakers is another nobody seems to have mentioned...

recently i was fixing one (it worked a bit) but then i put it down on the workbench and it pulled to the vice.. doesnt work at all now..

that me for you..
