What effect does the rotating magnetic field have on the rotor?

Thus the current flowing in the rotor produces magnetism and interacts with the magnetism produced by the stator winding. Thus a rotating magnetic field created forces the rotor to spin.

When a conductor is stationary and the magnetic field is moving or changing the emf induced is called?

Static induced EMF: When the conductor is stationary and the field is changing (varying) then the emf induced in the conductor is called static induced EMF.

Why the coil rotates in a magnetic field?

The coil (called armature) is mechanically rotated in the uniform magnetic field by some external means. The rotation of the coil causes the magnetic flux through it to change, so an emf is induced in the coil. The ends of the coil are connected to an external circuit by means of slip rings and brushes.

How does change in magnetic flux induced current?

A current can be induced in a conducting loop if it is exposed to a changing magnetic field. In other words, if the applied magnetic field is increasing, the current in the wire will flow in such a way that the magnetic field that it generates around the wire will decrease the applied magnetic field.

Why the rotor is forced to rotate in the direction of rotating magnetic field?

As in when it cuts the rotor, currents are induced on the rotor as per faraday law of electromagnetism(rotor is stationary and flux is changing) these rotor currents further create their own magnetic flux such that it would reduce the cause(lenz law) this causes the rotor rotate in the direction of rotating magnetic …

How a rotating magnetic field makes the rotor of an induction motor rotate?

The rotating magnetic field is produced radially around the rotor by the varying currents in the stator windings. The rotating magnetic field induces eddy currents in the squirrel cage’s vertical bars causing it to rotate. The rotation of the rotor and magnetic field are asynchronous.

Does the change in magnetic flux induce current or EMF?

Due to change in magnetic flux, e.m.f. is always induced, but induced current will flow only when the circuit is complete.

Does change in magnetic flux induced EMF or current?
