Magnetic Loop Antenna This Is The Physics Loop Antenna Magnetic Field Question?

Physics Loop Antenna Magnetic Field Question? - magnetic loop antenna this is the

Building a TV antenna from the ground up, and you want to use a diameter of 8 cm from the antenna loop of copper in the design. They know that the TV signal most of the stations in their vertical polarization, and that most are transferred in a mountainous NE Loop. A representative of the TV station broadcasts on a frequency of 195 MHz amplitude variations of the electric field due to the location of the station signal is above 30 V / m.

a) What is the magnitude and direction of the magnetic field variations on the television in your area?

b) Explain how your antenna must be oriented to receive the maximum signal.

c) amplifier to the antenna design is needed to predict, measure the voltage between points A and B, if there is a small gap between the points. Use the information provided by the representative of the station to see that people expect the maximum voltage that can be between 2 points.

Drawing d) It is the magnetic field several timesthe magnetic field of the television, and is oriented in the direction approximately the same position. Explain why not result in Earth's magnetic field about issues with your antenna.
