Figure P19.64 is a setup that can be used to measuremagnetic fields. A rectangular coil of wire contains N turnsand has a width w. The coil is attached to one arm of a balanceand is suspended between the poles of a magnet. The fieldis uniform and perpendicular to the plane of the coil. Thesystem is first balanced when the current in the coil is zero.When the switch is closed and the coil carries a current I, amass m must be added to the right side to balance the system.(a) Find an expression for the magnitude of the magneticfield and determine its direction. (b) Why is the result independentof the vertical dimension of the coil? (c) Supposethe coil has 50 turns and width of 5.0 cm. When the switch is closed, the coil carries a current of 0.30 A, and a mass of 20.0 gmust be added to the right side to balance the system. What isthe magnitude of the magnetic field?

The artery in the figure has an inside diameter of 2.75 mm and passes through a region where the magnetic field is 0.067 T. If the voltage difference between the electrodes is 186 μV , what is the speed of the blood? Express your answer using two significant figures.
