Name something that uses a magnet apart from fridge,boardgame orcupboard doors?
Answers:
a compass
Speakers
Magnet crane
magnetic tank bag
speakers , induction motor , clip on shades , jewelry , overhead cranes , MRI machines in hospitals , also used to find cracks in metal
Electric motor, compass.
compus
speackers
magnetic screwdriver
TVs and computer monitors use magnets to direct the electron beams as they 'draw' the image.
Speakers of any style use magnets to vibrate the speaker cone.
Hard drives for computers use magnets both to store data and to move the red head.
Cassette players, reel-to-reel tape, VHS players, etc. use magnets in the read/write heads to work with the magnetic-based media.
MRI machines use huge magnets to scan the human body.
Junk yards and factories use magnets to pick up and move metals.
Electricity. Ever heard of electromagnets? I've heard of them but I don't actually know what they're used for. It increases something, possibly current. Although I've been told that you can produce electricity by waving a wire between a magnet(s), if this helps.
a tv
electrical components
magnet therapy
Particle accellerator
Bullet trains
Sorry I have the best answer for this question...
It's without a doubt 'Etch A Sketch'

Compass. TV. Computer. Stereo. Magna Doodle.
'Magnetic' trains as employed in Japan and Germany. The repelling qualities of equal poles keeps the train suspended in the air above the track. This dramatically reduces friction, alllowing the train to travel at speeds close to 200mph.
a reed switch.
or a maglev train.
geomag
a computer hard drive.
a floppy disk drive
a radio transmitter
a magneto found in sme electric moters
tape recorder
Yes, almost all of these things, but NOT a compass (or compuss as one poor soul spells it!). The needle in a compass is attracted to the Earth's magnetic pole but is not itself a magnet - it would be useless if it were!
magnetic letters, funnily enough. Formerly made by Fisher Price, now made by just about everyone.
magnet is used to generate electrcity, current is produced when a changing magnetic field is placed in an electric field.
it is also used to measure currents in a circuit ( ameter)
store memory(magnetic tape disk)
A toy Motor, Head Phone speakers,
frictionless bearings - where the rotor is held in suspension by electromagnets allowing shafts to rotate at higher speeds than previously attained
