When current flows in a conductor there is a magnetic field formed around the conductor. This magnetic field can be used to make an electric magnet (like the ones used at junkyards), motors also use magnetism to operate, and many switches (solenoid, motor starters, and relay switches) use magnetism to open or close.
Not magnetic
Magnetic: Fridge magnet Non magnetic: Milk
Non magnetic!!
It non magnetic
The electromagnets that are used in junkyards are called just that, electromagnets. They are used to sort out different types of metals.
Try Texas Junk Yards @ http://www.texas-junkyards.com, its a city based search for junkyards .. very simple
Electromagnets are useful because some machines need magnets that can stop being magnetic. In junkyards, some machines need to pick up metallic objects, so they need magnets that can turn on and off, which is where a electromagnet becomes useful.
Of course I can! Junkyards are a great place to find scrap metal, scrap parts when remodeling or building a car, and even getting rid of the junk you don't need anymore
There are many places one can go to see pictures of junkyards filled with cars. One of the most popular places to go for pictures of anything is Google images.
Most auto junkyards salvage usable engine parts. Know your make, model, year, and any other details about your engine and call the local auto junkyards.
Junkyards will sell just about anything they have. Junkyards take cars and trucks so as long as they have the truck you need they will sell you the part.

Dealerships or junkyards.
The purpose of a lanfill is to dispose of more trash than regular dumps or junkyards.
Try your local junkyards. They may have one.
Magnets are everywhere - junkyards, things that go on your fridge, even the fridge itself!
