Electric current induced within the conductor by changing magnetic field, which flows in closed loops within the conductor is known as? Correct Answer Eddy current

The correct answer is Eddy current.

  • Eddy currents are loops of electrical current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction.

Key Points

  • The first person to observe eddy currents was Francois Arago, the 25th Prime Minister of France, who was also a mathematician, physicist and astronomer.
  • Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field.
  • They can be created when a conductor is moving through a magnetic field, or when the magnetic field surrounding a stationary conductor is varying.
  • The magnitude of the current in a given loop is directly proportional to the strength of the magnetic field, the area of the loop, and the flux rate.
  • On the other hand, it is inversely proportional to the resistivity of the material.
