Circular loop of a wire and a long straight wire carry currents I0 and Ie respectively as shown in the figure. Assuming that these are placed in the same plane, the magnetic
fields will be zero at the centre O of the loop, when separation H is
- \(\frac{I_{e} R}{I_{c} \pi}\)
- \(\frac{I_{e} R}{I_{e} \pi}\)
- \(\frac{I_{c} R}{I_{e} \pi}\)
- \(\frac{I_{c} \pi}{I_{c} R}\)
Answer
(A) I_ e R I_ c
