Figure is a cross-sectional view of a coaxial cable. The center conductor is surrounded by a rubber layer, which is surrounded by an outer conductor, which is surrounded by another rubber layer. In a particular application, the current in the inner conductor I 2 is 6.00 A out of the page and the current in the outer conductor I 1 is 2.00 A into the page. Assume that l = 1.80 mm. Determine the magnitude and direction (upward or downward of the page) of the magnetic field at point b. (Choose upward of the page as the positive y-direction and express the magnetic field by using the sign of the result, which must be in µT and without decimals. That means if you get a result of a 922 and the direction of the field is upward of the page, just type 922 or if you find the direction of the field as downward of the page, just tpe -922 in the answer box.

Some types of bacteria containchains of ferromagnetic particles parallel to their long axis. The chainsact like small bar magnets that align these magnetotactic bacteria withthe earth’s magnetic field. In one experiment to study the response ofsuch bacteria to magnetic fields, a solenoid is constructed with copperwire 1.0 mm in diameter, evenly wound in a single layer to form a helicalcoil of length 40 cm and diameter 12 cm. The wire has a very thinlayer of insulation, and the coil is wound so that adjacent turns are justtouching. The solenoid, which generates a magnetic field, is in an enclosurethat shields it from other magnetic fields. A sample of magnetotacticbacteria is placed inside the solenoid. The torque on an individualbacterium in the solenoid’s magnetic field is proportional to the magnitudeof the magnetic field and to the sine of the angle between the longaxis of the bacterium and the magnetic-field direction What current is needed in the wire so that the magnetic field…
