What kinds of electromagnets are in scrap yards?
well really all what it does is pick up metal bits off of cars or other things that are magnetics and than you cane move it to were you want to :)
List three uses for electromagnets?
1. Scrap yards sometimes use it to lift heavy pieces of MAGNETIC materials e.g steel. 2. In speakers they use electro-magnets so the speaker can actually play the sound. It is used in the speakers diaphragm. 3. In hospitals to remove magnetic particles from a patients eye after a accident. hope this helps!!Lucy:)
Electromagnets are generally weaker than permanent magnets?
Depends on the size. One good example of a powerful electromagnet is the one used to lift cars at junk yards. Permanent magnets are not used for that due to the sheer power needed to lift cars. Also, electromagnets can be turned ON and OFF making them useful in picking up and then dropping the junk cars as needed. Another big example of electromagnets are the ones used on power generators to generate electric power.
How are electromagnets found?
In almost all rotary electrical equipment, and associated with much equipment that is not itself electric - in things such as alternators/dynamos.

How do scrap yards separate metals from non magnetic metals?
They use electromagnets to separate magnetic metals from non-magnetic metals/materials in scrapyards.

Application that electromagnetic cranes have over standard cranes?
Usually in junk-yards handling scrap iron and steel. Only problem is some steel alloys- like stainless, are non-magnetic not attracted to the electromagnets.
How are magnets used in junk yards?
Rather than "permanent" magnets, the large electromagnets used in junkyards only create a magnetic field when electric current flows through them. They are used to lift iron and steel scrap, and to separate it from non-magnetic scrap. The cranes have an electric generator connected to a wire coil in the large round lifting disc. When the power is on, its magnetic field attracts heavy iron and steel to it. When the scrap is positioned where they want it, they cut the power to the electromagnet and the scrap drops. They are attached to cranes and are used to lift up heaps of scrap metal
Can you show examples of electromagnetic change?
Electromagnets are used in places like scrap yards! to separate metals
What type of things can be found at a scrap yard?
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.
Where are electromagnets used?
fire bells tv's junk yards and a lot more
Where are the Avro Arrow prototypes?
all destroyed in scrap yards
Can people go and buy metal from scrap yards?
yes
How might one dispose of a totaled car?
A vehicle that has been totaled can be sold for scrap and parts through junk yards or scrap metal yards. Also there are several businesses that will pay a small amount of money to take the scrap from a totaled car.
Are there any junk yards in San Antonio that buy scrap metal?
The only salvage yards in San Antonio that I could find that buy scrap metal were Newell Salvage, River City Steel, and Ashley Salvage. For their locations I would simple yellowbook the address and while there could look for more salvage yards that buy scrap metal.
