A pair of stationary and infinitely long bent wires are placed in the x-y plane as shown in Figure. The wires carry cu'rrent of 10 ampere each as shown. The segment L and M are along the x-axis. The segment P and Q are parallel to the Y-axis such that OS = OR = 0.02 m. Find the magnitude and direction of the magnetic induction atthe origin O. |

Answer» Solution :Since point 0 is along the length of segments L and M the field at O DUE to these TWO segments will be ZERO `therefore` Magnetic field at O is due to QS and RP. `B_(SQ) = (mu_0)/(4pi) xx (I)/(OS) odot = 10^(-7) xx (10)/(0.02) odot` `B_(RP) = (mu_0)/(4pi)xx(I)/(OR) odot = 10^(-7) xx (10)/(0.02) odot` `therefore B_0 = B_(SQ) + B_(RP) = 10^(-7) xx (10)/(0.02) xx 2 odot` `10^(-4)T odot` |
