QUESTION: 1

According to Faraday’s laws of electromagnetic inductance, an emf is induced in a conductor whenever?

Solution:

An emf is induced, according to Faraday’s laws of electromagnetic inductance, whenever the conductor in a magnetic field cuts the magnetic lies of flux, varying the flux per unit area, and hence the magnetic field which induces an emf.

QUESTION: 2

 Direction of induced emf is determined by __________

Solution:

Fleming’s left hand rule stated that if the index finger points towards magnetic flux, the thumb towards the motion of the conductor, then the middle finger points towards the induced emf.

QUESTION: 3

“The direction of an induced e.m.f. is always such that it tends to set up a current opposing the motion or the change of flux responsible for inducing that e.m.f.”, this is the statement for?

Solution:

The above statement is that of Lenz’s law. It is used to determine the direction of the induced emf.

QUESTION: 4

According to Fleming’s right hand rule, the thumb points towards?

Solution:

Fleming’s left hand rule stated that if the index finger points towards magnetic flux, the thumb towards the motion of the conductor, then the middle finger points towards the induced emf.

QUESTION: 5

According to Fleming’s right hand rule, the index finger points towards?

Solution:

 Fleming’s left hand rule stated that if the index finger points towards magnetic flux, the thumb towards the motion of the conductor, then the middle finger points towards the induced emf.

QUESTION: 6

According to Fleming’s right hand rule, the middle finger points towards?

Solution:

Fleming’s left hand rule stated that if the index finger points towards magnetic flux, the thumb towards the motion of the conductor, then the middle finger points towards the induced emf.

QUESTION: 7

The relation between direction of induced emf and direction of motion of the conductor is?

Solution:

According to Fleming’s right hand rule, the induced emf, the motion of the conductor and the magnetic flux are mutually perpendicular.

QUESTION: 8

The relation between direction of induced emf and direction of magnetic flux is _______

Solution:

According to Fleming’s right hand rule, the induced emf, the motion of the conductor and the magnetic flux are mutually perpendicular.

QUESTION: 9

 The relation between direction of magnetic flux and direction of motion of the conductor is _______

Solution:

According to Fleming’s right hand rule, the induced emf, the motion of the conductor and the magnetic flux are mutually perpendicular.

QUESTION: 10

North pole induces __________

Solution:

A north pole will always induce an anti-clockwise current whereas a south pole will always induce a clockwise current due to electromagnetic theory.
