Cold. If magnets get overheated, they can cease to work all-together.
magnets also provide humans with the required materials to create products to help and improve our day to day life, things such as tv, fridge, computer etc all use magnets to help them work. compasses are also essential and without magnets we could not have them. also in case you are not aware, without magnetism we could not have atoms etc.. and therefor we would not exist.
Water, wood, and plastic are all non-magnetic. Magnets will not attract them.
tv,washing machines,hoovers,phones,doorbells and tape recorders all use an electro magnet.
You could get a range of equipment from running machines to exercise bikes to rowing machines these all help towards you keeping healthy and fit, they also work very well.

Since the machines did nearly all the work, but the people still needed to man the machines so jobs were actually gained by machines and the work was easy, but dangerous.
