An aluminum bar moves with a speed 2m/s between two copper roads in a magnetic field of 2T as indicated on the figure. The distance between the cooper roads is 10m. The aluminum bar is always in contact with cooper roads and moves without friction. A voltmeter is coupled between the roads. What is the potential measured by the voltmeter (in volt), if the resistance of the rods and aluminum bar are consider to be negligible?

A spark can jump between two nontouching conductors if the potential difference between them is sufficiently large. A potential difference of approximately 940 V is required to produce a spark in an air gap of 1.0 x 104 m. Suppose the light bulb in the figure is replaced by such a gap. How fast would a 2.55-m rod have to be moving in a magnetic field of 6.03 T to cause a spark to jump across the gap? Number Units X X X x X x X M X Conducting rail X
A device called a railgun uses the magnetic force on currents to launch projectiles at very high speeds. An idealized model of a railgun is illustrated in (Figure 1).

True or False A moving charge entering a magnetic field parallel to the field will move in a straight line. A man whose resistance is 10,000 Ω has 120 volt potential difference across his body. This would cause a fatal shock. Adding resistors to a parallel circuit decreases the equivalent resistance. The resistance of a resistor increases with decreased temperature The terminal voltage (V) of a battery is always less than its EMF (ξ). The electric field E is a scalar but the electric potential V is a vector.
