Answer:
The average emf that will be induced in the wire loop during the extraction process is 37.9 V
Explanation:
The average emf induced can be calculated from the formula

Where
is the number of turns
is the change in magnetic flux
is the time interval
The change in magnetic flux is given by

Where
is the final magnetic flux
and
is the initial magnetic flux
Magnetic flux is given by the formula

Where
is the magnetic field
is the area
and
is the angle between the magnetic field and the area.
Initially, the magnetic field and the area are pointed in the same direction, that is, 
From the question,
B = 1.5 T
and radius = 15.0 cm = 0.15 m
Since it is a circular loop of wire, the area is given by

∴ 

∴

( NOTE:
)
Wb
For 
The field pointed upwards, that is
. Since 
Then

Hence,


From the question

Here,
= 1
Hence,
becomes


Hence, the average emf that will be induced in the wire loop during the extraction process is 37.9 V.
