3. A rod of mass M and length L can slide without friction on two parallel rails as shown in the figure. There is a uniform magnetic field B directed out of the plane. The rails have negligible resistance but the rod has resistance R. Initially the rod is at rest, but at time t = 0 the switch is closed connecting the rod to a battery of Ɛ volts. Find the velocity of the rod as a function of time.

A metal rod of mass m carrying a current I glides on two horizontal rails a distance d apart. If the coefficient of kinetic friction between the rod and rails is k, what vertical magnetic field is required to keep the rod moving at a constant speed?
Is Ampere’s law valid for all closed paths? Why isn’t it normally useful for calculating a magnetic field?
Repeat Exercise 22.41, but with the loop lying flat on the ground with its current circulating counterclockwise (when viewed from above) in a location where the Earth’s field is north, but at an angle 45.0° below the horizontal and with a strength at 6.00105T.
Does increasing the magnitude of a uniform magnetic field through which a charge is traveling necessarily mean increasing the magnetic force on the charge? Does changing the direction of the field necessarily mean a change in the force on the charge?
Make a drawing and use RHR—2 to find the direction of the magnetic field of a current loop in a motor (such as in Figure 22.34). Then show that the direction of the torque on the loop is the same as produced by like poles repelling and unlike poles attracting.
Explain why the magnetic field would not be unique (that is, not have a single value) at a point in space where magnetic field lines might cross. (Consider the direction of the field at such a point.)
A circular loop of wire is held in a uniform magnetic field, with the plane of the loop perpendicular to the field lines. Which of the following will not cause a current to be induced in the loop?

Two long, parallel wires each carry the same current I in the same direction (Fig. OQ30.4). Is the total magnetic field at the point P midway between the wires (a) zero, (b) directed into the page, (c) directed out of the page, (d) directed to the left, or (e) directed to the right?
In a region a non-uniform magnetic field exists such that Bx=0,By=0,andBz=ax where a is a Constant. At some time t, a wire of length L is carrying a current I is located along the x-axis from origin to x = L. Find the magnetic force on the wine at this instant in time.
Sodium ions (Na+) move at 0.851 m/s through a blood-stream in the arm of a person standing near a large magnet. The magnetic field has a strength of 0.254 T and makes an angle of 51.0 with the motion of the sodium ions. The arm contains 100 cm3 of blood with a concentration of 3.00 1020 Na+ ions per cubic centimeter. If no other ions were present in the arm, what would be the magnetic force on the arm?
