I tried to find one but was unable to.
It is a magnet which moves metal around the scrap yard. Scientific explanation = It s a big round magnet which is actually an electromagnet. This allows the magnet to be turned on then off. When turned on the electromagnet attracts any magnetic substances. This is why most cars are made of something magnetic! You can move this electromagnet around because it is a crane you pick stuff up move it and then drop it by turning the electromagnet off!
The types of things that can be found in a scrap yard depend on the type of scrap yard it is. Many scrap yards deal with just automotive scrap so one would find spare parts for cars there. Other scrap yards deal with just metals such as copper.
The cicuit at first is all conected when it is turned on then the person driving the machine will turn the engine off and the circuit will disconnect causeing the magnet not to keep hold of the metal.
1-800-237-3463 is the number to call to find the numbers to any scrap yard you are looking for.
An electromagnet is used in an electrical engine, but an electrical engine contains normal magnets too.
An electromagnet - is essentially a metal 'core' encased in wire. When power is applied to the wire, the core becomes magnetic - when the power is turned off, the magnetism is lost. Think along the lines of a crane in a scrap-yard. The crane has an electromagnet attached to its lifting arm. The operator switches on the magnet to lift a load of scrap metal, and switches it off to drop the load.
If you mean is it illegal to take a hard drive from a scrap yard- it may be. The scrap in the scrap yard belongs to the scrap yard- like everything else there. Taking the property of someone else is called theft. However, it the operator of the scrap yard sells or gives the hard drive to you, you should be OK.
There are many useful car parts that can be found in a scrap yard and then sold at a reduced price. Some of these items include tires, batteries, and speakers.
