They use electromagnets to separate magnetic metals from non-magnetic metals/materials in scrapyards.

Why are electromagnets used in metal scrap yards?

Electromagnets are used in metal scrap yards because they can easily pick up and sort large quantities of ferrous metals from non-ferrous metals. By using an electric current to create a magnetic field, electromagnets attract and collect ferrous metals such as iron and steel, allowing for efficient separation and processing of different types of metals.


Why do scrap yards advertise for non ferrous metals?

Scrap yards advertise for non-ferrous metals because they are valuable and in demand for recycling. Non-ferrous metals, such as copper, aluminum, and brass, are often found in items like wiring, pipes, and household appliances, which can be brought to scrap yards for cash payment. Recycling non-ferrous metals also helps conserve natural resources and reduce waste in landfills.


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


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.


What happens inside a scrap heap magnet?

Scrap heap magnets are basically electromagnets. Electromagnets are simply wire coils usually would around an iron core. When connected to a DC voltage or current source, the electromagnet becomes energized, creating a magnetic field just like a permanent magnet. The magnetic flux density is proportional to the magnitude of the current flowing in the wire of the electromagnet.


Who will give you daily scrap metal recycling prices?

I collect scrap metals and bring to scrap recycling yards. How can I be sure I'm getting the best price for my efforts? Where do you find the current prices that tha scrap yards are getting for their scrap? There are many pay for and free sources of current scrap metal prices. Most scrap metal prices are based upon Comex and LME pricing less a percentage. If you call the scrap yard or recycling yard, ask them for their current prices and they will gladly provide. Just know what type of scrap metal you have so they can give you the prper pricing.


How does an electromagnet work and what are its practical applications?

An electromagnet works by using electricity to create a magnetic field. When an electric current flows through a coil of wire, it generates a magnetic field around the coil. This magnetic field can attract or repel other magnetic materials. Practical applications of electromagnets include use in electric motors, generators, MRI machines, speakers, and magnetic levitation trains. They are also used in industrial settings for lifting and moving heavy objects, in scrap yards for sorting metals, and in magnetic separators for separating materials.


Where can one look to find listings for local scrap yards?

There are a few methods available for finding a local scrap yard in your area. You could use your local Yellow Pages to find scrap yards closest to you. You can also find local scrap yards using the iPhone app called iScrapApp.


Can you show examples of electromagnetic change?

Some examples of electromagnetic change include electrical currents flowing through wires, light waves traveling through space, and magnetic fields attracting or repelling objects. These phenomena demonstrate the interaction between electric and magnetic fields as described by Maxwell's equations.


How much are catalitic converters worth as scrap?

The value of catalytic converters as scrap can vary significantly based on their specific make, model, and the precious metals they contain, such as platinum, palladium, and rhodium. On average, scrap catalytic converters can be worth anywhere from $50 to over $1,000 each, depending on these factors. Prices can fluctuate based on market demand and the current prices of the metals involved. It's advisable to check with local scrap yards for the most accurate and up-to-date valuations.
