Which device can be used as electromagnet?
Electricity and Magnetism | Short/Long Answer Questions
Solution: Electromagnet is used in electrical appliances such as electric bell, radio, TV, fan and motors .
What safety device uses an electromagnet?
A ground fault interrupter (GFI) is a safety device found in updated kitchen and bathroom wiring that works based on electromagnetic induction. GFIs compare the currents in the live/hot and neutral wires.
What equipment do you need to make an electromagnet?
- Large iron nail (approximately 3 inches in length)
- Thin coated copper wire.
- Dry cell batteries.
- Electric tape.
- Iron fillings, paper clips and other magnetic items.
What are 3 uses of electromagnets?
- Motors and generators.
- Transformers.
- Relays.
- Electric bells and buzzers.
- Loudspeakers and headphones.
- Actuators such as valves.
- Magnetic recording and data storage equipment: tape recorders, VCRs, hard disks.
- MRI machines.
What are the 3 parts of an electromagnet?
There are three main parts required to build an electromagnet: the iron core, copper wire, and an electricity source . Changes in each of these pieces of the electromagnet will influence the overall strength of the magnet.

Can you make your own electromagnet?
Electromagnets can be created by wrapping a wire around an iron nail and running current through the wire . ... The electric field in the wire coil creates a magnetic field around the nail. In some cases, the nail will remain magnetised even when removed from within the wire coil.
How is an electromagnet made Class 6?
Answer: An electromagnet is made by wrapping a coiled wire around a rod of iron . Magnetic strength increases with the increase in number of turns in the coil.
What is the function of electromagnet?
An electromagnet is a device that sends electricity through a coil of wire to produce a magnetic field . This leads to a magnet that can be controlled – turned on and off with the flip of a switch, or increased or decreased in strength. The coils are often wrapped around a regular magnet to make it stronger.
How are electromagnets used in daily life?
In the home, by far the most common use of electromagnets is in electric motors . Think of all of those bits of electrical equipment with some kind of electric motor: vacuum cleaners, refrigerators, washing machines, tumble driers, food blenders, fan ovens, microwaves, dish-washers, hair driers.
Does refrigerator use electromagnet?
Many common household items contain electromagnets. An electromagnet is only magnetic when it has electricity flowing through it. ... Electronic devices such as refrigerators, washing machines, lamps, telephones, TV’s, stereos, and many other electronic appliances use electromagnets to help them work a certain way.
