What are the arrangement of moving magnets and wire coil called?
electromagnet
When would an electromagnet stop working?
An electromagnet would stop working if the electrical current flow is interrupted or if the power supply is disconnected. Additionally, if the coil overheats, it can damage the insulation and cause the electromagnet to fail.
What is an electromagnet junkyard crane called?

What has an electromagnet in it?
a school bell, the earths core and a junkyard magnet
When was the electromagnet invented?

Where was the electromagnet invented?
British electrician David Sandy invented the electromagnet in 1825 when he was bored.
Who invented the electromagnet?
jake marshall
Who invented the original electromagnet?
The original electromagnet was invented by the Englishman William Sturgeon in 1825. It was much improved by the American Henry in 1830.
When was the electrometer invented?
The first electromagnet was invented in 1825.

How can mechanical energy can be converted into electricity?
That is what an electric motor does. A relay also does this, as does a big lifting electromagnet in a junkyard.
Who invented the first electromagnet motor?
British scientist William Sturgeon invented the electromagnet in 1824.[7][8] His first electromagnet was a horseshoe-shaped piece of iron that was wrapped with about 18 turns of bare copper wire
How does a crane use electromagnet?
A crane or junkyard crane uses an electromagnet to pick magnetic items up. The crane controls the electromagnet by using a a circuit that has a wire wrapped around a piece of metal that can be magnetized that's at the end of the crane's arm. When the circuit completes, the metal at the end of the cranes arm gets temporarily magnetized. When the current stops, the metal get demagnetized and can't pick things up anymore.
How does a car scrap heap magnet work?
Scrap Heap MagnetUsually the kind of magnet a junkyard uses is an electromagnet. An electromagnet is simply an iron core wrapped around by copper wire. Then current runs through the wire, it becomes a very strong magnet. There are other types, but I think electromagnet is the most common for car scrap heap.
