A straight conductor is moving across a uniform magnetic field. Which of the following does not affect the value of induced emf in the conductor?
Answer:
The induced electromotive force (emf) in a straight conductor moving across a uniform magnetic field is governed by Faraday’s law of electromagnetic induction. Several factors can affect the value of induced emf, but one factor that does not affect the value of induced emf is the resistance of the conductor.
The factors that influence the induced emf in a straight conductor moving across a magnetic field include:
- The strength of the magnetic field.
- The speed of the conductor moving through the magnetic field.
- The length of the conductor cutting through the magnetic field lines.
- The angle between the conductor and the magnetic field direction.
The resistance of the conductor, however, does not directly affect the value of induced emf. The induced emf is primarily dependent on the rate of change of magnetic flux, which is related to the factors mentioned earlier. Therefore, the resistance of the conductor does not play a role in determining the magnitude of the induced emf in this scenario.
