How do household goods use magnets?
Speakers and motors use magnets. Using electricity, the electromagnets create a magnetic force which reacts against the permanent magnets in these devices, thus creating motion. Magnets are used in cabinet latches to help them to stay closed. Screwdriver tips are sometimes magnetized to help hold the screw on the end or to help retrieve a dropped screw. Magnets are often used to hold things onto metal objects. Refrigerator magnets are one example. Common objects may have magnets attached to hold them onto refrigerators and...

Asked in Waste and Recycling, Science, Chemistry
How can magnets be used in recycling cans?
Magnets will pick up steel cans, lifting them away from a solid waste stream. Additionally, rapidly changing magnetic fields can be used to "pop" other metals out of a solid waste stream, through current induced in those metals. ...
