Web25 jan. 2024 · Ans: The magnetic field on the axis of a current-carrying loop is given by: \ ( {B_x} = \frac { { {\mu _0}I {R_x}^2}} { {2 { {\left ( { {x^2} + {R^2}} \right)}^ {3/2}}}}\widehat i\) where \ (x\) is the distance of that point on the axis from the centre of the loop, \ (R\) is the radius of the loop, and \ (I\) is the current flowing in the loop.
WebThus, the magnetic field at P due to the entire circular loop is B = B x i ^ = μ 0 I R 2 2 ( x 2 + R 2) 3 2 i ^ When x=0, we may obtain the field at the center of the loop B 0 = μ 0 I 2 R … WebIt was formulated by Heinrich Lenz in 1833. While Faraday's law tells us the magnitude of the EMF produced, Lenz's law tells us the direction that current will flow. It states that the direction is always such that it will oppose the change in flux which produced it.
