Question

A current element of 2 milliampere meter is at the corner. A of a unit cube ABCDEFGH, the element being along AB. Calculate the field at the remaining seven corners of the cube (figure 1.5).

Answer 1

Correct Answer - At B,B=0; at C,B `=0.7 xx 10^(-10) T` along `vecGC;` at D,B`=2 xx 10^(-10)`T along `vecHD` ; at E,B`=2 xx 10^(-10)` T perpendicular out of the plane ABG ; at H,B `=2 xx 10^(-10) T` out of the plane ABH
