# A magnet of length 10 cm and magnetic moment $1 Am^2$ is placed along the side AB of an equilateral triangle ABC. If the length of sides AB is 10 cm, the magnetic induction at point C is :

$\begin {array} {1 1} (1)\;10^{-7}T & \quad (2)\;10^{-5}T \\ (3)\;10^{-4}T & \quad (4)\;10^{-9}T \end {array}$

Can you answer this question?

(3) $10^{-4}T$
