Q1:

What is the flux density in a magnetic field in which the flux in 0.1 m2 is 600 Wb?

A 6,000 T

B 600 T

C 600 T

D 6 T

ANS:A - 6,000 T

Flux density (B) = flux/Area of cross section (A)
B = Weber/Meter Square = Tesla.
B = 600*10^-6/0.1,
= 6000*10^-6,
= 6*10^-3,
= 0.006.
Or
B = 6000*10^-6 Tesla.
