A) \[\frac{{{\mu }_{{}^\circ }}I}{\pi r}\]
B) \[\frac{2{{\mu }_{{}^\circ }}I}{\pi r}\]
C) \[\frac{{{\mu }_{{}^\circ }}I}{2\pi r}\]
D) \[Zero\]
Correct Answer: D
Solution :
[d] \[{{B}_{1}}=\frac{{{\mu }_{{}^\circ }}I}{2\pi \left( \frac{d}{2} \right)}\otimes \,into\text{ }the\text{ }plane\] \[{{B}_{2}}=\frac{{{\mu }_{{}^\circ }}I}{2\pi \left( \frac{d}{2} \right)}\odot \,into\text{ }the\text{ }plane\] \[{{B}_{net\,}}={{B}_{1}}-{{B}_{2}}\] \[=0\]You need to login to perform this action.
