A long straight wire, carrying a current of 200A , runs through a cubical wooden box, entering and leaving through holes in the centres of opposite faces Figure. The length of each side of the box is 20cm . Consider an element PQ of the wire of 1cm long at the centre of the box. Calculate the magnitude of the magnetic field produced by this element at the points A, B, C and D as shown in figure. The points A, B and C are at the centres of the faces of the cube and the point D is at the mid point of one edge.
