Principle of electromechanical energy conversion forces and torq

What is the purpose of a magnetic field system in electromechanical energy conversion?

• To create a force for converting mechanical energy into sound energy

• To create a force for converting electrical energy into mechanical energy, or vice versa.

• To generate heat for converting electrical energy into light energy

• To produce light for converting mechanical energy into electrical energy

Explain the concept of flux linkage in magnetic field systems.

• The force exerted by a magnetic field on a current-carrying wire

• The resistance of a material to the flow of magnetic flux

• The amount of energy stored in a magnetic field

• Product of the number of turns in a coil and the magnetic flux passing through the coil

How does a magnetic field system contribute to the generation of electrical energy?

• By increasing the temperature of the conductor

• By creating a gravitational force

• By inducing an electric current in a conductor

• By reducing the resistance in the circuit

Describe the process of electromechanical energy conversion in a generator.

• Electrical energy is converted to mechanical energy through the rotation of a coil within a magnetic field.

• The process involves converting sound energy into electrical energy.

• The generator uses chemical energy to produce electrical energy.

• Mechanical energy is converted to electrical energy through the rotation of a coil within a magnetic field.

What are the factors that affect the force experienced by a current-carrying conductor in a magnetic field?

• Strength of the magnetic field, current flowing through the conductor, length of the conductor, and angle between the direction of the current and the magnetic field

• Type of material used for the conductor

• Temperature of the conductor

• Color of the conductor

Explain the relationship between torque and magnetic field strength in an electromechanical system.

• Torque has no relationship with the magnetic field strength.

• Torque is inversely proportional to the magnetic field strength.

• Torque is directly proportional to the magnetic field strength.

• Torque is only related to the electric field strength.

How is torque calculated in a magnetic field system?

• torque = magnetic field strength * magnetic moment * sin(theta)

• torque = magnetic field strength / magnetic moment * sin(theta)

• torque = magnetic field strength - magnetic moment * sin(theta)

• torque = magnetic field strength + magnetic moment * sin(theta)

What are the different methods used to increase the torque in an electromechanical system?

• Increasing current in the motor, increasing the number of turns in the coil, and using gears or pulleys to increase mechanical advantage

• Decreasing current in the motor, decreasing the number of turns in the coil, and using smaller gears or pulleys

• Using a smaller motor, reducing the number of windings in the coil, and using a weaker mechanical advantage

• Reducing the current in the motor, decreasing the number of turns in the coil, and using friction to decrease mechanical advantage
