A rubber band is covered with a conducting and current passed through it in the direction as shown in the figure. What happens, when it is placed in the magnetic field vecB shown in the figure

Two insulating infinitely long wires are lying mutually perpendicular to each other as shown in the figure. If the two wires carry currenst I_1 and I_2 as shown in the figure, find the magnetic field at point P (A,b).
