A conducting sheet lies in a plane perpendicular to a magnetic field B that is below the sheet. If B oscillates at a high frequency and the conductor is made of a material of low resistivity, the region above the sheet is effectively shielded from B . Explain why. Will the conductor shield this region from static magnetic fields?
A cyclometer is a device mounted on a bicycle that records and displays trip information such as elapsed time, distance traveled, and average speed. Modern versions employ small magnets attached to a spoke on either the front or rear wheel and a sensor located on the front fork or rear frame. As the magnet is carried past the detector once each wheel revolution, it produces an electrical pulse that is recorded and logged by an integrated circuit in the device. The distance traveled equals the total number of revolutions multiplied by the circumference of the wheel. (a) A typical mountain bike has a wheel diameter of 26 in. How far will a cyclist have traveled in both miles and kilometers if her cyclometer indicates that her front wheel has made 25,000 revolutions during her trip? (b) If the cyclometer clock shows that the elapsed time for the trip was 2 hours and 40 minutes, what was the rider’s average speed during this period?
Integrated Concepts The Tethered Satellite discussed in this module is producing 5.00 kV, and a current of 10.0 A flows. (a) What magnetic drag force does this produce if the system is moving at 7.80 km/s? (b) How much kinetic energy is removed from the system in 1.00 h, neglecting any change in attitude or velocity during that time? (c) What is the change in velocity if the mass of the system is 100,000 kg? (d) Discuss the long term consequences (say, a week-long mission) on the space shuttle’s orbit, noting what effect a decrease in velocity has and assessing the magnitude of the effect.

Integrated Concepts One long straight wire is to be held directly above another by repulsion between 1heir currents. The lower wire carries 100 A and the wire 7.50 cm above it is 10gauge (2.588 mm diameter) copper wire. (a) What current must flow in the upper wire, neglecting the Earth’s field? (b) What is the smallest current if the Earth’s 3.00105T field is parallel to the ground and is not neglected? (c) Is the supported wire in a stable or unstable equilibrium if displaced vertically? If displaced horizontally?
Why is the direction of the current shown in each part of Figure 24.6 opposite to the electric field produced by the wire’s charge separation?

Imagine that there is 0.8 A running through a metal (7.6 x1028 electrons/m3) wire with a square cross-sectional area of width 0.6 cm. We also place this wire into a uniform magnetic field, such that a potential difference of 6.5 x 10-8 V is across the wire (from one edge to the other, as we discussed in class on the Hall Effect). What is the magntiude of this magnetic field?
Please answer with complete solution.A beam of electrons (of charge −e and mass me) is shot into a region of uniformmagnetic field with a speed of 35 m/s. They exit the region of uniform magnetic field opposite the direction they had entered. How strong must the magnetic field be such that each electron stayed in the region for a total of 70 ms? Answer should be in me/qe unit.
A rail gun used electromagnetic forces to accelerate a projectile to very high velocities. The basic mechanism of acceleration is relatively simple and can be illustrated in the following example. A metal rod of mass m and electrical resistance R rests on parellel horizontal rails (that have negligible electric resistance) which are distance L apart as shown in figure 1. The rails are also connected to a voltage source delta V, so a current loop is formed. The vertical magnetic field, initially zero, is slowly increased. When the field strength reaches the value B0, the rod, which was intially at rest, begins to move. Assume that the rod has a slightly flattened bottom so that it slides instead of rolling. Use g for the magnitude of all the free fall acceleration. (A) find the coefficient of static friction between the rod and the rails.
