Answer:
(a)The average of magnetic flux trough each turns is wb.
(b) The magnitude of mutual inductance of the two solenoid is H.
(c)The magnitude of emf induced in the outer solenoid by changing current in the inner solenoid is 0.027132 v .
Explanation:
Given that,
The number of turns of the solenoid=N₁= 350
The diameter of the solenoid=D= 2.20 cm=0.022
The length of the solenoid is = = 22.0 cm=0.22 m
The second solenoid with = 21 turns which is wound around the solenoid at its center.
The current in the inner solenoid is = 0.150 A and is increasing at a rate of 1700 A/s i.e
A/s
(a)
The formula of magnetic field of a solenoid is
T
So, the magnetic flux of each turns
wb
The average of magnetic flux trough each turns is wb.
(b)
Since the both coil wound tightly. So, the magnitude magnetic flux though each turns of both coils is same.
The mutual inductance of the two solenoid is
H
(c)
The formula of emf is
v
=0.027132 v
The emf induced in the outer solenoid by changing current in the inner solenoid is 0.027132 v .
