FOAK: Magnets in the house

Can anyone think of 5 uses for magnets in the house. I've done the
fridge door and speakers but need another three. I need to know where
they are used and what they are doing.

...and yes. I _am_ asking for help with my 8 year old son's homework

 

Do electro-magnets count? Door bell.

 

Computer hard disc drives.

A picture frame I've got attaches it's back with magnets.

The front of my fireplace in the living room also attaches with
magnets.

 

Magnetic knife rack in kitchen
As part of any electric motor
Kitchen cupboard doors

 

...and what do they do?

Oooh when did you get that?

 

In some electric motors.

In some temperature-controlled devices (the Curie Effect).

In some computer keyboards (the Hall Effect).

 

Got any on the fuel lines in your car or bike?

Anything wiv an electric motor.

Anything with a relay/solenoid.

 

Cupboard doors, anything with an electric motor, some types of
electronic scales, vital components of the 'magnetron' in a
microwave...

Work like a speaker with a coil of wire, but move a read / write head
across the disk instead of moving a bit of paper / plastic in and out.

 

I notice no girlies have replied...

What?

 

Storing pins, if there's a sewing machine in the house. Erase head on
cheap cassette recorder. Cupboard door catches. Magnetic pick-up
tools. Magnetic screwdriver. Most DC motors - I'm assuming just
permanent magnets here.

Outside the house: compass.

 

Magnetic pick-up tool, the infamous 'magnet-onna-stick' that TOG
should have remembered.

Magnetic wrist bands that are supposed to counteract
travel/seasickness and arthiritis.

The compass wot every boy should have.

The little magnet in the handle of a decent screwdriver that holds the
screw to the tip.

The stylus of your record player.

In your microphones.

The magnetic strip on your credit cards.

In televisions and monitors.

Take your pick.

 

Door latches.

 

Tin openers have them, 'lectric ones do anyway. Cupboard doors.

 

Read and write the data to the patter by arranging particles or summat
like that.

Ah. Suddenly I understand.
