# Which statement describes the relationship between electric generators and electric motors?

Contents

Generators transform mechanical energy into electrical energy whereas electric motors transform electric energy into mechanical energy.

## Which of the following is true about the relationship between electricity and magnetism?

Which of the following is true about the relationship between electricity and magnetism? Magnetism is based on how gravity attracts electrical energy. Magnetism and electricity cannot be converted into one another. Electricity can be used to create a magnet.

## Which of the following is a definite way to decrease the magnetic field of the electromagnet?

Answer: The correct answer is: A. straightening the wire, because the number of turns of the wire around the iron core is directly proportional with the strength of electromagnet.

## What is the function of an electric generator in terms of electric power and motion?

Think of a generator as an ‘energy engine’ that converts kinetic (motion) energy into electricity. A generator consists of a stationary magnetic field (stator) in which a rotating electromagnet (armature) spins to produce electrical current.

## What is the function of an electromagnet in an electric doorbell quizlet?

What is the function of an electromagnet in an electric doorbell? It attracts a metal striker, which then hits the bell.

## What is the relationship between electromagnetic 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.

## What is the importance of electricity and magnetism in our daily life?

Electricity and magnetism are two very important topics in the science of physics. We use electricity to power computers and to make motors go. Magnetism makes a compass point North and keeps notes stuck onto our refrigerators.

## Which makes an electromagnet work?

Electromagnets are made of coils of wire with electricity passing through them. Moving charges create magnetic fields, so when the coils of wire in an electromagnet have an electric current passing through them, the coils behave like a magnet.

## Which devices use electromagnets?

Electromagnets are very widely used in electric and electromechanical devices, including:

• Motors and generators.
• Transformers.
• Relays.
• Electric bells and buzzers.
• Actuators such as valves.
• Magnetic recording and data storage equipment: tape recorders, VCRs, hard disks.
• MRI machines.

## How do you strengthen an electromagnet?

You can make an electromagnet stronger by doing these things:

1. wrapping the coil around a piece of iron (such as an iron nail)
2. adding more turns to the coil.
3. increasing the current flowing through the coil.

## What are the similarities and difference between electric motor and generator?

The Difference Between Electric Motor and Electric Generator in Tabular Form

Electric Motor Electric Generator
The shaft of the motor is driven by the magnetic force generated between the armature and the field. In electric generators, the shaft is attached to the rotor and is driven by the mechanical force.

## What is the primary difference between an electric motor and an electric generator?

Converting energy from one form to another is the key to understanding the differences between electric motors and generators. An electric motor converts electricity into mechanical energy, providing a power source for machinery. A generator does the opposite of this, converting mechanical energy into electricity.

## What are the three basic parts of an electric generator?

The main components of an electric generator can be broadly classified as follows:

• Engine.
• Alternator.
• Fuel System.
• Voltage Regulator.
• Cooling and Exhaust Systems.
• Lubrication System.
• Battery Charger.
• Control Panel.
