- (Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) Describe the three basic interactions between electricity and magnetism.An electron in a TV CRT moves with a speed at 6.00107m/s, in a direction perpendicular to the Earth’s field, which has a strength of 5.00105T. (a) What strength electric field must be applied perpendicular to the Earth’s field to make the election moves in a straight line? (b) If this is done between plates separated by 1.00 cm, what is the voltage applied? (Note that TVs are usually surrounded by a ferromagnetic material to shield against external magnetic fields and avoid the need for such a correction.)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?

- What is electromagnetic induction? Who invented it and how does it work?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.1 ,Gauss and circulation theorems for the magnetic induction vector? 2.
