Electromagnets are used by doctors to remove iron splinters because they can generate a magnetic field strong enough to attract and pull out the iron fragments from the body without the need for invasive procedures. This non-invasive method is effective in safely retrieving the splinters, minimizing tissue damage and reducing the risk of infection.

Why is electromagnets better than permanent for collecting scrap iron?
Electromagnets can be turned on and off, allowing for easier control and manipulation of scrap iron. They can generate a stronger magnetic force than permanent magnets, making them more effective at attracting and holding onto large amounts of scrap iron. Additionally, electromagnets can be customized to vary the strength of the magnetic field as needed for different applications.
What types of magnets are produced by running current through a soft iron core?
When current is run through a soft iron core, an electromagnet is produced. This type of magnet can be turned on and off by controlling the flow of electricity. Soft iron cores are often used in electromagnets because they can quickly magnetize and demagnetize.
Why steel is not used in electromagnets?
Steel is not ideal for electromagnets because it has low electrical conductivity and high hysteresis loss, which reduces the efficiency of the electromagnet. Instead, materials that have higher electrical conductivity, such as iron or soft magnetic materials like iron-nickel, are preferred for electromagnets. These materials provide better magnetic properties, allowing the electromagnet to generate a stronger magnetic field.
Why electromagnets are made of soft iron?
Electromagnets are made of soft iron because it has high magnetic permeability, which allows it to easily become magnetized and demagnetized when a current is passed through the wire coil surrounding it. This property results in a strong magnetic field that can be controlled by the flow of electricity, making soft iron ideal for electromagnet applications.
How do you use a sentence about electromagnets with an iron bar and copper coil?
When an electric current flows through the copper coil, it creates a magnetic field around the coil due to electromagnetic induction. This magnetic field attracts the iron bar and causes it to behave like a magnet.
Does an iron box use electromagnets?
no there is no use of electromagnets in iron box
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.
Why is an electromagnet only suitable for removing iron or steel splinters?
An electromagnet, or any magnet, only attracts certain metals like iron. (Steel is a kind of iron.) If you want to remove, for example, aluminum splinters, you must use another process because aluminum is not attracted to a magnet.
What do electromagnets attract?
Unlike normal magnets, electromagnets attract just someof the alloys that contain iron, such as steel and iron, but not all of them. Electromagnets do not attract aluminium, copper, titanium,brass, bronze, tin, nickel, platinum, gold, silver, lead or pewter.Contrary to some opinions, electromagnets cannot attract cardboard.See also the related question.
What common alloy is used to make magnets?
Iron is used for electromagnets.
Why is electromagnets better than permanent for collecting scrap iron?

How do electromagnets find uses in a vending machine?
Electromagnets are used in vending machines to deciever real coins from fake ones. Electromagnets will sort counterfeit money from real money, because most counterfeit money is an iron alloy. Iron is magnetic and gets pulled by the electromagnet, while real coins are not effected.
What metals can electromagnets pick up for example stell etc.?
Iron, Cobalt and Nickel.
What are some object are magnets?
electromagnets are used in batteries to convert energy into electricity
What is a magnet that can turn on and off what is it made of?
Electromagnets, they are usually made of a iron core and a warping of copper.
How are both permanent magnets and electromagnets used in a motor?
They both are strong and are made of iron and steel.
Will an electromagnetic be attracted to the same things as a regular metal?
Yes, electromagnets can attract for example iron.
