In the given diagram, two coils of insulated copper wire are wound over a nonconducting cylinder as shown. Coil P has larger number of turns.

Flemings right hand rule explains:

A

Direction of magnetic field

B

Direction of motion of conductor

C

Only (a)

D

Both (a) and (b)

Text Solution

Verified by Experts

The correct Answer is:
D
In Fleming.s Right Hand Rule the first three fingers of the right hand are mutually perpendicular to each other such that the forefinger gives the direction of magnetic field and the thumb points in the direction of the motion of a conductor then, the middle finger will give the direction of the induced current

    1200 turns of copper wire are wound onto a cardboard cylinder 60 cm 160 long and 5 cm diameter. What is the inductance of the coil?

    Assertion (A) : When two coils of enamelled copper wire are wound on each other, the mutual inductance between the coils is maximum. Reason (R) : Mutual inductance does not depend on the orientation of the coils.

    Answer question numbers (a)-(d) on the basis of your understanding of the following paragraph and the related studied concepts : The phenomenon of electromagnetic induction is the production of induced current in a coil placed in a region where the magnetic field changes with time. The magnetic field may change due to a relative motion between the coil and a magnet placed near to the coil. If the coil is placed near to a current carrying conductor, the magnetic field may change either due to a change in the current through the conductor or due to the relative motion between the coil and conductor. The direction of the induced current is given by the Fleming's right-hand rule. State Fleming's right-hand rule.
