In which situation shown in Figure\({\rm{24}}{\rm{.24}}\)will the electromagnetic wave be more successful in inducing a current in the wire? Explain.

Short Answer

Expert verified

In situation (a) the electromagnetic wave will be more successful in including a current in the wire.

Step by step solution

01

Given data

Figure 24.24

02

Define Electromagnetic Induction

Magnetic or electromagnetic induction is the process of producing an electromotive force across an electrical conductor in a shifting magnetic field. Michael Faraday discovered induction in\({\rm{1831}}\), which James Clerk Maxwell formally defined as Faraday's law of induction.

03

Explanation

The electric field in diagram (b) is perpendicular to the wire's length, but in diagram (a), the field oscillates along the wire's length. As a result, in diagram (a), an alternating current is formed along the entire length of the wire, but in diagram (b), it is only created along the diameter. Furthermore, if a charge is not already in motion, the magnetic field has no effect on it, and if it is, the magnetic force acts perpendicular to the motion, so pointing it in the direction of the wire has no effect.

Therefore, diagram (a) will have the electromagnetic wave successfully including the current in a wire.

Assume the mostly infrared radiation from a heat lamp acts like a continuous wave with wavelength 1.50μm. (a) If the lamp’s 200-Woutput is focused on a person’s shoulder, over a circular area 25.0cmin diameter, what is the intensity inw/m2? (b) What is the peak electric field strength? (c) Find the peak magnetic field strength. (d) How long will it take to increase the temperature of the 4.00-kgshoulder by 2.00°C, assuming no other heat transfer and given that its specific heat is 3.477×103J/kg.°C?

(a) Calculate the range of wavelengths for AM radio given its frequency range is \(540\) to \(1600{\rm{ }}kHz\). (b) Do the same for the FM frequency range of \(88.0\) to \(108{\rm{ }}MHz\).

Conversations with astronauts on lunar walks had an echo that was used to estimate the distance to the Moon. The sound spoken by the person on Earth was transformed into a radio signal sent to the Moon and transformed back into sound on a speaker inside the astronaut's space suit. This sound was picked up by the microphone in the space suit (intended for the astronaut's voice) and sent back to Earth as a radio echo of sorts. If the round-trip time was 2.60 s , what was the approximate distance to the Moon, neglecting any delays in the electronics?

If electric and magnetic field strengths vary sinusoidally in time, being zeroatt=0at , then E=E0sin2πft and B=B0sin2πft. Let here.(a) When are the field strengths first zero? (b) When do they reach their most negative value? (c) How much time is needed for them to complete one cycle?

An AM radio transmitter broadcasts 50.0 kw of power uniformly in all directions. (a) Assuming all of the radio waves that strike the ground are completely absorbed, and that there is no absorption by the atmosphere or other objects, what is the intensity 30.0 km away? (Hint: Half the power will be spread over the area of a hemisphere.) (b) What is the maximum electric field strength at this distance?
