# A magnet of length $10\; cm$ and magnetic moment $1\; Am^2$ is placed along side AB of an equilateral triangle ABC. If the length of the side AB is $10\; cm$. The magnetic induction at the point 'C' is :<br> $(\mu_0 = 4 \pi \times 10^{-7} Hm^{-1})$
( A ) $10^{-9}$
( B ) $10^{-7}$
( C ) $10^{-5}T$
( D ) $10^{-4}T$
