The device shown in the figure allows you to measure the rate of blood flow in the vessels of the human body, since the blood contains electrically charged ions. Suppose that the blood vessel measures 2.0 mm in diameter, that the magnetic field is 0.080 T and that the fem measurement is 0.10 mV. Is this statement True or False? N S Voltímetro
c. What is the resistance of the coil given that the diameter of the wire is 2.00 mm? (Recall, resistance of wire is given by R = ρL/A, where ρ is the resistivity of the metal, L is the length of the wire, and A is the cross-sectional area.)
Suppose you have a long, skinny conductor that is oriented with its long axis parallel to a uniform magnetic field. Suppose also that the conductor is moving along its long axis in a straight line at constant velocity v. Despite the motion of the conductor, no motional emf is induced. Why? The magnetic field is too uniform The velocity has no component normal to the magnetic field The velocity is too low The conductor is so long and so thin that its electrical resistance is too high

A pickup truck has a width of 80.0 in. If it is traveling north at 35 m/s through a magnetic field with vertical component of 37 ?T, what magnitude emf is induced between the driver and passenger sides of the truck? mV
A single loop of copper wire, lying flat in a plane, has an area of 7.20 cm2 and a resistance of 1.80 N. A uniform magnetic field points perpendicular to the plane of the loop. The field initially has a magnitude of 0.500 T, and the magnitude increases linearly to 1.50 T in a time of 1.12 s. What is the induced current (in mA) in the loop of wire over this time? 3.57 You may have neglected to convert units. Be sure to convert the area from cm2 to m2. Then, convert the current from A to mA. mA Need Help? Read It
