A) 0.904 Wb
B) \[\lambda \]
C) \[\frac{\lambda }{4(\mu -1)}\]
D) \[\frac{2\lambda }{4(\mu -1)}\]
Correct Answer: B
Solution :
\[\mu ={{\mu }_{0}}(1+\chi )\] or \[\mu =4\pi \times {{10}^{-7}}(1+599)\] or \[\mu =7.536\times {{10}^{-4}}Tm{{A}^{-1}}\] \[B=\mu H=7.536\times {{10}^{-4}}\times 1200T\] \[f=BA=7.536\times {{10}^{-4}}\times 1200\times 0.2\times {{10}^{-4}}Wb\] \[=1.81\times {{10}^{-5}}Wb\]You need to login to perform this action.
