In the figure, two long straight wires at separation d = 7.41 cm carry currents of i1 = 4.98 mA and i2 = 4.00 i, out of the page. (a) At what coordinate on the x axis in centimeters is the net magnetic field due to the currents equal to zero? (b) If the two currents are doubled, is the zero-field point shifted toward wire 1, shifted toward wire 2, or unchanged? .X (a) Number Units v (b)In the figure, point P2 is at perpendicular distance R = 21.1 cm from one end of straight wire of length L = 12.4 cm carrying current i = 0.689 A. (Note that the wire is not long.) What is the magnitude of the magnetic field at P2? R R Number i ! Units T v Save for Later Last saved 20 minutes ago.

A second long wire is perpendicular to the xy plane, passes through the point (0, 6.5 m, 0), and carries a current of 60 A in the positive z direction. What is the magnitude of the resulting magnetic field at the point (0, 0.80 m, 0)? Number i Units
