JEE Main 2007 Physics question
Two identical conducting wires AOB and COD are placed at right angles to each other. The wire AOB carries an electric current and COD carries a current . The magnetic field on a point lying at a distance ' d ' from O, in a direction perpendicular to the plane of the wires AOB and COD, will be given by
Answer: (2)
Solution
The point is at perpendicular distance d from each (long) wire, giving fields and . Each field is perpendicular to its own wire and to the line from O, so the two fields are
