A magnetising field produces a magnetic flux of `2.2xx10^(-5)` weber in an iron bar of cross section `0.5 cm^(2)`. What is the magnetic induction?

A

`4.4" Wb/m"^(2)`

B

`2.2xx10^(-2)" Wb/m"^(2)`

C

`4.4xx10^(-4)" Wb/m"^(2)`

D

`0.44" Wb/m"^(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`B=phi/A=(2.2xx10^(-5))/(0.5xx10^(-4))=4.4xx10^(-1) =0.44" Wb/m"^(2)`
