The answer should be in pico not in micro that is 917 pT.

Flux density = flux / cross - sectional area.

Lets solve it
We have given flux density=5.5*10^-6 wb
And cross sectional area= 6*10^-3 m^2

We take
B=Q/A
B=flux density in tesla(T)
Q=magnetic flux in weber(wb)
A=cross section area in square metre

B=5.5*10^-6/6*10^-3 =(5.5*10-3)/6 =0.9166666 *10^-3

If you round of then you will be get

B=917microT ANS

Actually Siba Padhi is wrong Nd chandraprakash is right

Siba padhi said:   1 decade ago
You are wrong chandraprakash.

Flux density =Q/A^2

Farmula
B=Q/A
B=Flux density,Q=flux,A=cross sec. Area
