The number of coils wound around an iron cylinder which is rotated in the magnetic field is called

Correct answer: B. Armature

  • A. Slip rings
  • B. Armature
  • C. Commutator
  • D. Electromagnet

Explanation

B is the correct answer.The number of coils wound around an iron cylinder, which is rotated in a magnetic field to induce an electromotive force (EMF), is called the armature. It is a crucial component in devices like electric generators and motors.

About Electromagnetism

Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
