Current Attempt in Progress Figure [a] shows an element of length d: = 1.21 pm in a very long straight wire carrying current. The current in that element sets up a _, dilterential magnetic field 5' B at points in the surrounding space. Figure {till gives the magnitude dB 01 the Field idr points 5.5 cm from the element. as a lunctien at angle Qbetween the wire and a straight line to the point. The itiertical scale is set by d3: = .531] pT. 1ii'liihat is the magnitude of the magnetic eld set up by the entire wire at perpendicular distance 5.5 cm from the wire? am. is a u are x 3 [null [M Number n Units v The figure below shows two very long straight wires (in cross section) that each carry a current of 3.68 A directly out of the page. Distance d1 = 5.00 m and distance d2 = 4.50 m. What is the magnitude of the net magnetic field at point P, which lies on a perpendicular bisector to the wires? -OP Number i UnitsIn the figure, two long straight wires (shown in cross section) carry currents i1 = 21.1 mA and iz = 25.9 mA directly out of the screen. They are equal distances from the origin, where they set up a magnetic field B. To what value must current in be changed in order to rotate B 22.60 clockwise?
