Electromagnets are used in scrapyards to lift and transport metal objects. When an electric current passes through the coil of wire in the electromagnet, it creates a magnetic field that attracts ferrous materials like iron and steel. This makes it easier to handle and sort large quantities of scrap metal efficiently.

How do electromagnets in scrapyards work?
Electromagnets in scrapyards work by running an electrical current through a coil of wire, creating a magnetic field. This magnetic field attracts ferrous metals, such as iron and steel, allowing the electromagnet to lift and move metal objects. When the current is turned off, the magnetic field dissipates and the metal objects are released.
Why is an electromagnet considered to be a temporary magnet?
An electromagnet acts as a magnet only while electricity is passing through the coil. Once the electricity is turned off, the electromagnet ceases being a magnet. Electromagnets are much used in scrapyards. Attached to a crane, metal is picked up and deposited into railway wagons, or road haulage vehicles, to be sent for recycling.
What device can be used to determine the direction of the magnetic field in the electromagnet?
A compass can be used to determine the direction of the magnetic field in an electromagnet. The needle of the compass will align along the direction of the magnetic field lines produced by the electromagnet.
What is the strength of an electromagnet proportional to?
The strength of an electromagnet is proportional to the number of turns in the coil, the amount of current flowing through the coil, and the magnetic permeability of the core material used in the electromagnet. Increasing any of these factors will increase the strength of the electromagnet.
How can you make an electromagnet rotate?
To make an electromagnet rotate, you can place it in the proximity of a permanent magnet. When a current flows through the electromagnet, it interacts with the magnetic field of the permanent magnet, causing the electromagnet to rotate. This setup can be used in devices like electric motors and generators.
A magnet can be switch on and off?
An electromagnet can - for example in scrapyards where a crane picks up a car with power on, then drops it when power switched off.

Where can you find a helicopter control stick from a junked bird?
There are aircraft scrapyards where these are easy to get. Search "aircraft surplus", "aviation scrapyards", etc.

How much co2 is produced by scrapyards?
The amount of CO2 produced by scrapyards can vary based on factors such as the size of the operation, the types of machinery used, and the transportation of materials. Generally, scrapyards emit CO2 through activities like burning fuels for equipment, transportation of scrap metal, and processing of materials. Implementing sustainable practices like energy-efficient machinery and recycling can help reduce CO2 emissions.

Where can I find wrecked cars for sale?
No, but generally local junkyard and scrapyards that often tow in wrecks will be willing to part with them if offered cash. It is possible to find local scrapyards online.
Where are the two types of electromagnet and a bar magnet commonly used?
I'm not sure where a bar magnet is used, but an electromagnet is used in junkyards, and in some laboratories.
What kind of magnet is used in the hotel room door?
Electro Magnetic is correct
What is an example of a sentence using the word electromagnet?
Electromagnets are widely used now. Instead of traditional magnets.
What device can be used to determine the direction of the magnetic field in the electromagnet?
A compass can be used to determine the direction of the magnetic field in an electromagnet. The needle of the compass will align along the direction of the magnetic field lines produced by the electromagnet.
