What does the electromagnet in an electric motor do apex?

In an electric motor, how do the permanent magnets and the electromagnet. … The electromagnet causes the permanent magnets to reverse. poles.

What does the electromagnet in an electric motor do?

An electric motor is a device that uses an electromagnet to change electrical energy to kinetic energy. When current flows through the motor, the electromagnet rotates, causing a shaft to rotate as well. The rotating shaft moves other parts of the device.

How do you make an electric motor more powerful?

We can increase the turning force (or torque) that the motor can create in three ways: either we can have a more powerful permanent magnet, or we can increase the electric current flowing through the wire, or we can make the coil so it has many “turns” (loops) of very thin wire instead of one “turn” of thick wire.

What happens within the motor when an electric current?

What happens within the motor when an electric current flows through the. … An electric field produces mechanical energy, which causes the. loop to produce electrical energy.

Which is an important step in how an electric motor uses magnetic force to produce motion?

Answer: The north pole of an electromagnet placed in the center of a permanent magnet repels the north pole of the permanent magnet. Explanation: The commutator of the electric motor reverses the current in each half revolution to keep the torque, turning the coil in the same direction.

Which statement describes how electrical power is calculated?

Power equals current divided by voltage, o. C. Power is the product of voltage and current.

What is the relationship between electromagnet and electric motor?

Electric Motors

When an electric current flows through a loop or coil of wire, placed between the two poles of an electromagnet, the electromagnet exerts a magnetic force on the wire and causes it to rotate. The rotation of the wire starts the motor. As the wire rotates, the electric current changes directions.

Is electromagnet a permanent magnet?

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. … However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.

What is principle of an 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.

What do you think is the role of the electric motor in the materials appliances?

Answer: The role of electric motor is to converts electrical energy into mechanical energy, so that it can operate the appliances.
