What is an excavator magnet?

How much does a scrap yard magnet weigh?

The standard line includes models ranging from 30 inches to 72 inches in diameter. LDSA magnets range in weight from 1,025 to 7,750 pounds, with lifting capacity from 625 to 5,625 pounds.

How does a scrap yard magnet work?

The scrap heap magnet is basically a giant electromagnet that is powered by a very large battery. It works the same way an ordinary electromagnet works. Thick insulated copper wire is wound around a soft iron core. The magnetic power of an electromagnet depends upon the current and the number of turns in the coil.

Why do junk dealers use magnets?

Wrecking yards employ extremely powerful electromagnets to divide ferrous recyclables from non-ferrous materials, and move those scrap metals or even entire cars from one place to another. This creates a magnetic field around the coiled wire, magnetizing the metal as if it were a permanent magnet.

What is a junkyard magnet called?

One example of a lifting magnet is a junkyard magnet — a type of temporary magnet otherwise known as an electromagnet.

Are old magnets worth money?

How powerful is a junkyard magnet?

A junkyard magnet might be almost as powerful (about 1 T), but a refrigerator magnet is several hundred times smaller (5 mT). The earth’s magnetic field is a hundred times smaller still, varying from about 30 μT at the equator to about 70 μT at the poles.

What is the strongest magnet in the world?

The strongest permanent magnets in the world are neodymium (Nd) magnets, they are made from magnetic material made from an alloy of neodymium, iron and boron to form the Nd2Fe14B structure.

Are Neodymium magnets worth money?

The current bid price of neodymium oxide is $50 per kg and praseodymium oxide is $55 per kg. Other REE are even more expensive – e.g., the dysprosium bid price is $266 per kg and terbium $517 per kg (Kitco 2019).
