Assertion An induced emf of 2 V is developed in a circular loop, if current in the loop is changed at a rate of 4 `As^(-1)` .IF 4 A of current is passed through this loop, then flux linked with this coil will be 2 Wb.
Reason Flux linked with the coil is
`|phi|=|(e)/(di//dt)|i`

A

If both Assertion and Reason are corrent and Reason is the corrent explanation of Assertion.

B

If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.

C

If Assertion is true but Reason is false.

D

If Assertion is false but Reason is ture.

Text Solution

Verified by Experts

The correct Answer is:
A
`L=(-e)/(di//dt)rArrL=2//4=1//2`
On putting values, we get
`phi=LirArr phi=(1)/(2)xx4=2Wb`

A long solenoid having n = 200 turns per metre has a circular cross-section of radius a_(1) = 1 cm . A circular conducting loop of radius a_(2) = 4 cm and resistance R = 5 (Omega) encircles the solenoid such that the centre of circular loop coincides with the midpoint of the axial line of the solenoid and they have the same axis as shown in Fig. A current 't' in the solenoid results in magnetic field along its axis with magnitude B = (mu)ni at points well inside the solenoid on its axis. We can neglect the insignificant field outside the solenoid. This results in a magnetic flux (phi)_(B) through the circular loop. If the current in the winding of solenoid is changed, it will also change the magnetic field B = (mu)_(0)ni and hence also the magnetic flux through the circular loop. Obvisouly, it will result in an induced emf or induced electric field in the circular loop and an induced current will appear in the loop. Let current in the winding of solenoid be reduced at a rate of 75 A //sec . Magentic flux through the loop due to external magnetic field will be I is the current in the loop a_(1) is the radius of solendoid and a_(1)=1cm (given) a_(2) is the radius of circular loop and a_(2)=4cm (given) i is hte current in the solenoid
