Question

A coil of area 2m² placed perpendicular to the uniform magnetic field of 0.1T find the
magnetic flux linked with coil. If the coil is rotated by 90° in 2 seconds. How much
the emf is produced in the coil?​

Answer 1

Answer:

$emf \: = \frac{change \: in \: flux}{change \: in \: time} \\ emf \: = \frac{d(bacos \beta)}{dt} \\ emf \: = \frac{2 \times 0.1 \times \cos(0) - \cos(90) }{2} \\ emf \: = 0.1$

hope the answer will help you

Answer 2

Answer:

$hope \: it \: helps \: you$

given,

d= 2

df= 2

formula,

emf=change in Flux/change in time

emf= d(bacos)

emf=(2×0.1×cos(0)-cos(90))/2

emf=0.1
