- Part A High-frequency signals are often transmitted along a coaxial cable, such as the one shown in the figure (Figure 1). For example, the cable TV hookup coming into your home is a coaxial cable. The signal is carried on a wire of radius R, while the outer conductor of radius Rą is grounded (i.e., at V = 0 V). An insulating material fils the space between them, and an insulating plastic coating goes around the outside. Find an expression for the capacitance per meter of a coaxial cable.

Recall that magnetic flux depends on magnetic field strength and the effective area the field is passing through. We'll start our investigation by looking at the field strength around a bar magnet. Position the magnet around the coil so that the region labeled A in the figure below is inside the coil. Move the magnet slowly back and forth and observe the effect on the brightness of the bulb and the needle of the voltmeter. Repeat the same process for the other two regions.
