Answer:
if it is a true or false, the answer is true
Explanation:
Answer:


-0.04194 V
Explanation:
= Number of turns in outer solenoid = 330
= Number of turns in inner solenoid = 22
= Current in inner solenoid = 0.14 A
= Rate of change of current = 1800 A/s
= Vacuum permeability = 
r = Radius = 0.0115 m
Magnetic field is given by

The average magnetic flux through each turn of the inner solenoid is 
Magnetic flux is given by

Mutual inductance is given by

The mutual inductance of the two solenoids is 
Induced emf is given by

The emf induced in the outer solenoid by the changing current inthe inner solenoid is -0.04194 V
