JEE Main2007PhysicsMagnetic Effects of CurrentActual
Two identical conducting wires A O B and C O D are placed at right angles to each other. The wire AOB carries an electric current I₁ and COD carries a current I₂ . The magnetic field on a point lying at a distance ' d ' from O , in a direction perpendicular to the plane of the wires A O B and C O D , will be given by
