If the areas under the `I-H` hysteresis loop and `B_H` hysteresis loop are denoted by `A_(1)` and `A_(2)`, then

A

`A_(2)=mu_(0)A_(1)`

B

`A_(2)=A_(1)`

C

`A_(2)=(A_(1))/(mu_(0))`

D

`A_(2)=mu_(0)^(2)A_(1)`

Text Solution

Verified by Experts

The correct Answer is:
A
As, `B=mu_(0)(H+l)`
`implies " "dB=mu_(0)dH+mu_(0)dl`
`"or "ointHdB=mu_(0)ointHdH+mu_(0)ointHdl`
`" "ointHdH=0`
`" "ointHdB=mu_(0)ointH.dl`
Area of the B-H loop `=mu_(0)xx` area of l - H loop
`i.e. " "A_(2)=mu_(0)A_(1)`

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
