How electromagnets are used to make electricity is because of the magnetic field that they give off around their core produces a small amount of electricity and if it is big enough it would give off enough power to generate a home. ( but who wants a magnet the size of an elephant in their back yard?!!!?)
What else can I help you with?
What is the only time that electromagnets magnetise?
Electromagnets are only magnetised while the electrical current is switched on.
Why are electromagnets cool?
Electromagnets are cool because they are reversible and can switch on and off, allowing for precise and rapid control. They are also lightweight and portable compared to permanent magnets. Additionally, electromagnets are versatile and can be found in many different applications, from MRI machines to speakers.
Can an electromagnet have an aluminum core?
No, aluminum is not suitable for use as a core in an electromagnet because it is not a ferromagnetic material. Electromagnets require a ferromagnetic core (such as iron or steel) to enhance magnetic induction and maintain magnetism when current is flowing through the coil.
What are the types of magnets?
Ferro-magnets, permanent magnets, temporary magnets, and electromagnets. Ferro-magnets are magnets that are magnetic at a higher temperature than room temperature. do not quote me on that. permanent magnets are magnets that are always magnets, they are the kinds you use a lot. Temporary magnets are things that are magnetic in an extrenal magnetic field. Last but not least, electromagnets. Electromagnets are coils of wire around a cobalt, nickel, or iron. When ou run electricity through the wire, the core and wire become magnetic.
Why is an armature made of iron?
An armature is made of iron because iron is a good conductor of electricity and has magnetic properties that make it ideal for use in electromagnets and electric motors. It allows for efficient transfer of electrical energy into mechanical energy when a current is passed through it.
What did people use electromagnets for in 1825?
-- laboratory experiments -- party tricks
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
What is one device that people use every day at school and at work that uses electromagnets?
what they use at work are computers TADA!!
What do factories use electromagnets for?
yes
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.
How are electromagnet usful?
Electromagnets are used in many ways. Televisions use electromagnets to direct the electron beam, whereas loudspeakers and earphones use electromagnets to push the diaphragm forwards.
How do you ancient Greeks use electromagnets?
The ancient Greeks understood magnets but since they did not have a source of electricity, they did not use electromagnets. They did make compasses.
How is electromagnet harmful for people?
Electromagnets are not harmful to people.
What are two common objects which contain electromagnets?
Two common objects that contain electromagnets are speakers and electric door locks. Speakers use electromagnets to convert electrical signals into sound waves, while electric door locks use electromagnets to control the locking mechanism.
Examples of electromagnets and their uses?
MRI machines use powerful electromagnets to produce detailed images of the inside of the body. Electric door locks use electromagnets to secure doors when electric current is applied. Maglev trains use electromagnets to achieve high speeds by levitating above the tracks without friction. Speakers use electromagnets to convert electrical signals into sound waves.
