Why do floating globes require power if they are magnetic?
because they use electromagnets whitch use power
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.
Why do MRI scanners use helium?
Liquid helium is used to cool the superconducting electromagnets.
Are all electromagnets magnetic?
All electromagnets are magnetic when they are turned on.
Why surgeons use electromagnets to remove iron bits from wounds?
Surgeons use electromagnets to remove iron bits from wounds because iron is magnetic, allowing it to be easily attracted and extracted using the magnet. This minimizes the risk of infection and reduces unnecessary tissue trauma that may occur with alternative removal methods. Electromagnets also provide a precise and efficient way to remove the foreign objects.
What are some devices that use electromagnetism?
Electromagnets in scrapyards are used to carry metal around. Electromagnets are better than normal magnets because you can turn the current on and off.
How do scrap yards separate metals from non magnetic metals?
They use electromagnets to separate magnetic metals from non-magnetic metals/materials in scrapyards.
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.
What are electromagnets used for in daily life?
Electromagnets are used in various applications in daily life, such as in doorbells, speakers, MRI machines, and magnetic locks on doors. They are also used in industries for lifting and moving metallic objects, like in scrapyards and manufacturing plants.
What are the some uses of electromagnets?
Electromagnets are used in scrapyards to pick up and drop metals that are magnetic because electromagnets are temporary which means you can turn it on and off. They are also used in hospitals and opticians to get metal out of your eye or body, You don't use a normal magnet because if you were in the middle of taking something out of someones eye you would need to be able to stop immediately in case you end up causing more damage.
Why is electromagnet used in a scrapyards?
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.
Does an iron box use electromagnets?
no there is no use of electromagnets in iron box
How do cat scans use electromagnets?
CAT Scan does not use electromagnets, its MRI (Magnetic Resonance Imaging) which uses Electromagnets to produce images of the patient's body.
Do ipods use electromagnets?
no
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.
Do fans use electromagnets?
Yes, some fans use electromagnets in their motors to generate the magnetic field needed for rotation. These electromagnets are energized by an electrical current to produce the desired magnetic force.
What do factories use electromagnets for?
yes
