Two circular wire loops are fixed in place as shown. counter-clockwise as viewed from above. a) Suppose we want the magnetic field to vanish at the common center of the loops. Should we generate a clockwise current in the small loop, or a counter-clockwise current? The large loop carries current io b) How strong a generate? (Hint: At the center of a circular current loop of radius R, the loop's magnetic field has magnitude Bloop, at center = poi / 2R.) * current will we need to 4a 6a

Determine the magnetic field at a point P located a distance x from the corner of an infinitely long wire bent at a right angle, as shown above right. The wire carries a steady current I.

Please answer both questions thank you!!!

Two long wires carry 10 A currents in the directions shown in the figure (Figure 1). One wire is 20 cm above the other. 1.  What is the magnitude of the magnetic field at a point halfway between them?  Express your answer with the appropriate units. 2. What is the direction of that magnetic field? A. Downward and to the right, at an angle of 45∘ from both wires. B. Upward and to the left, at an angle of 45∘ from both wires. C. Upward and to the right, at an angle of 45∘ from both wires. D. Downward and to the left, at an angle of 45∘ from both wires.
