Answer» Magnetic intensity is B = Explanation:In this question We have been given thatValue of the magnetic field is 0.34\times 10^{-4} T Deflected at an angle 30° So, we can find the value of magnetic intensity vector quantity pertaining to the condition at any point under the magnetic influence like an electric CURRENT, or an electromagnetic wave measured by the FORCE exerted on a vacuum upon a FREE unit NORTH pole placed at the point.magnetic intensity B = B = B = HENCE, Magnetic intensity is
