Please explain answers

Solution

here ,

A)

induced emf = rate of change of magnetic flux

as the magnetic flux is constant

c) A very strong magnet is in the centre of a conducting loop ,at rest

2)

for the induced current in the second loop ,

Using Lenz\'s law

the current in the second coil is

c) clockwise , upwards

5) Np = 200
Ns = 600

as Vin/Vout = Np/Ns = 200/600

Vout/Vin = 3

the correct option is c) 3 times

6)

as the output voltage is 3 times the input voltage

output voltage is increased

the correct option is a) increase the voltage
