What is a scrap yard magnet?

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!

Why would electromagnet be used in a recycling yard rather than a strong permanent magnet?

Because with an electromagnet, you can turn it off and on - you can pick things up with it then drop them again.

If an electromagnet was free to move how would it move?

Electromagnet is the magnet which is becoming active so long current through the coil flows. If current stops then the magnetism disappears. If a core made up of soft iron is used then magnetism will become more intense but the magnetism exists so long the current flows. Any way electromagnet will behave just like a permanent bar magnet. So electromagnet would set itself along the earth's magnetic meridian.

What is an advantage of using an electromagnet over a permanent magnet?

The advantage of an elecromagnet is that you can turn it on and off with a simple switch. So for example if you want to pick up a scrap car with a crane/electromagnet and move it, you can turn the electromagnet off when you want to release the car. You could not do the with a permanent magnet obviously.
