A simple electric motor can be built using a coil of wire that is free to rotate between two opposite magnetic poles. When an electric current flows through the coil, the coil experiences a force and moves. … When the electric current changes direction, the same end of the electromagnet becomes its south pole.
How does an electric motor work physics?
An electric motor converts electrical energy into physical movement. Electric motors generate magnetic fields with electric current through a coil. The magnetic field then causes a force with a magnet that causes movement or spinning that runs the motor.
How do motors work BBC Bitesize?
Electric motors use the forces produced by magnetic fields to produce a turning motion. If you put a length of wire in a magnetic field and pass a DC current through it (such as from a battery), the wire will move. … a coil of wire wrapped around something to support it. an axle for the coil of wire to spin around.
What is the motor effect GCSE physics?
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. The force increases if the strength of the magnetic field and/or current increases. …
Why does the coil turn in an electric motor?
A coil of wire carrying a current in a magnetic field experiences a force that tends to make it rotate. This effect can be used to make an electric motor.
What are the 6 parts of an electric motor?
These six components include:
- 1) The Rotor. The rotor is the moving part of your electric motor. …
- 3) The Bearings. The rotor in your electric motor is supported by bearings, which allow it to turn on its axis. …
- 4) The Windings. …
- 5) The Air Gap. …
- 6) The Commutator. …
- What Do All of These Components Have in Common?
Where do we use electric motors?
The largest electric motors are used for ship propulsion, pipeline compression and pumped-storage applications with ratings reaching 100 megawatts. Electric motors are found in industrial fans, blowers and pumps, machine tools, household appliances, power tools and disk drives.
What is a simple motor?
The basic idea of an electric motor is really simple: you put electricity into it at one end and an axle (metal rod) rotates at the other end giving you the power to drive a machine of some kind. … When an electric current starts to creep along a wire, it creates a magnetic field all around it.
What is Fleming’s left hand rule?
Fleming’s Left-Hand Rule is a simple and accurate way to find the direction of force/motion of the conductor in an electric motor when the magnetic field direction and the current direction are known.
What is Fleming’s left hand rule GCSE?
The force on a given length of wire in a magnetic field increases when: the current in the wire increases. the strength of the magnetic field increases.
What devices use the motor effect?
The most useful application of the motor effect is in the electric motor. Electric motors are used in things like washing machines, electric cars, hair dryers, CD players etc.
What is the consequences of 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 .
What does F BIL stand for?
F = BIL (f=force, b=magnetic field, i=current, l=length of conductor)

Does an electric motor transforms matter?
When a wire with a current is placed in a magnetic field, electrical energy is transformed into mechanical energy. … An electric motor transforms potential energy into mechanical energy.
What is the principle of electric motor?
The principle of an electric motor is based on the current carrying conductor which produces magnetic field around it. A current carrying conductor is placed perpendicular to the magnetic field so that it experiences a force.
