Determne the magnetic field due to a finit sraight wire of length 2l, carrying a steady current i. The point of interest P is l distance away from the middle point of wire O.
Solution) Here from given data the angle can be calculated which is 45degree, so from formulamagnetic field can be calculated easily..
