One of the important applications of electromagnetism is the electric motor. An electric motor converts electrical energy into physical movement. … The magnetic field then causes a force with a magnet that causes movement or spinning that runs the motor. Electric motors are used in all sorts of applications.
How is electromagnetism used in everyday life?
Electromagnets are found in doorbells, hard drives, speakers, MagLev trains, anti-shoplifting systems, MRI machines, microphones, home security systems, VCRs, tape decks, motors, and many other everyday objects.
Which part of the motor acts as an electromagnet?
Armature, Commutator and Brushes
The armature takes the place of the nail in an electric motor. The armature is an electromagnet made by coiling thin wire around two or more poles of a metal core. The armature has an axle, and the commutator is attached to the axle.
What is the motor effect used for?
A current-carrying wire or coil can exert a force on a permanent magnet. This is called the motor effect. The wire could also exert a force on another nearby current-carrying wire or coil.
Where is electromagnetism used?
Electromagnets are widely used as components of other electrical devices, such as motors, generators, electromechanical solenoids, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic separation equipment.
Why is electromagnetism so important?
Electromagnetism is a branch of physical science that involves all the phenomena in which electricity and magnetism interact. This field is especially important to electronics because a magnetic field is created by an electric current.
What are 3 parts of an electromagnet?
The basic components of an electromagnet are a wire and a power source. The power source may be AC (alternating current) or DC (direct current). The wire may be of any shape.
What are 3 ways to increase the strength of an electromagnet?
- wrapping the coil around a piece of iron (such as an iron nail)
- adding more turns to the coil.
- increasing the current flowing through the coil.
What are the 6 parts of an electric motor?
What is Electric motor ?
- Stator Coil.
- Rotor Coil.
- Main Shaft.
- Drive Pulley.
- Motor Housing.

What devices use the motor effect?
Electric motors are found in many household devices e.g. tumble dryers, washing machines, vacuum cleaners, electric knives, food mixers, hair dryers and electric toothbrushes. A coil of wire carrying a current in a magnetic field experiences a force that tends to make it rotate.
What causes the motor effect?
A wire carrying a current creates a magnetic field . This can interact with another magnetic field, causing a force that pushes the wire at right angles. This is called the motor effect .
Which two things are required for the motor effect?
(I) The angle formed between the wire and the direction of the magnetic field. (θ) The length of the wire, carrying the current, in the magnetic field.
How do you explain electromagnetism?
Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles.
Are electromagnets AC or DC?
A DC circuit has current circulating in one direction. … In alternating current (AC) electromagnets, used in transformers, inductors, and AC motors and generators, the magnetic field is constantly changing. This causes energy losses in their magnetic cores that are dissipated as heat in the core.
What is electromagnetism in simple terms?
Electromagnetism is a branch of Physics, that deals with the electromagnetic force that occurs between electrically charged particles. The electromagnetic force is one of the four fundamental forces and exhibits electromagnetic fields such as magnetic fields, electric fields, and light.
