As shown in the figure, a rectangular current loop is carrying current I = 3.0 A, in the direction shown, and is located near a long wire carrying a current Iw. The long wire is parallel to the sides of the rectangle. The rectangle loop has length 0.80 m and its sides are 0.10 m and 0.70 m from the wire, as shown. We measure that the net force on the rectangular loop as 4.9 × 10-6 N directed towards the wire. (a) What is the magnitude of the current Iw? [current] (b) In which direction does Iw flow: from top to bottom or from bottom to top in the sketch? [direction]

A tetrahedron has an equilateral triangle base with 20-cm-long edges and three equilateral triangle sides. The base is parallel to the ground, and a vertical uniform electric field of strength 200 N/C passes upward through the tetrahedron. (a) What is the electric flux through the base? [efluxtet] (b) What is the electric flux through each of the three sloping sides? [efluxsides]
