Help ~ Calculate the maximum noise voltage

In summary, the maximum noise voltage coupled into the circuit from the 10-gauss magnetic field at 60 Hz can be calculated using the equation for induced voltage around a wire loop. This value is estimated to be 377 uV.

Help!~ Calculate the maximum noise voltage

Homework Statement


Two conductors, each 10-cm long and space 1-cm apart, form a circuit.
This circuit is located where there is a 10-gauss magnetic field at 60 Hz.
What is the maximum noise voltage coupled into the circuit from the
magnetic field?

Homework Equations


From this book--Electromagnetic compatibility engineering- Chapter 2
http://books.google.com.hk/books?id...resnum=4&ved=0CDkQ6AEwAw#v=onepage&q&f=false"

The Attempt at a Solution


377uV

Does anyone could teach me how to calculate it?

Thank you!

The link does not appear to be translating...

In any case, what is the equation that you use to calculate the induced voltage around a wire loop from a changing magnetic field? That's what you should use here...

1. What is the maximum noise voltage and why is it important to calculate?

The maximum noise voltage is the highest possible voltage that can be produced by random fluctuations in an electrical circuit. It is important to calculate because it can affect the accuracy and reliability of the data collected in experiments or the performance of electronic devices.

2. How is the maximum noise voltage calculated?

The maximum noise voltage can be calculated using the root mean square (RMS) method, which takes into account the amplitude and frequency of the noise signal. It can also be calculated by measuring the noise voltage directly using a multimeter or oscilloscope.

3. What factors can affect the maximum noise voltage in a circuit?

The maximum noise voltage in a circuit can be affected by several factors such as temperature, resistance, and the type of electronic components used. High temperatures can increase the level of thermal noise, while low resistance and high frequency signals can increase the level of shot or flicker noise.

4. Can the maximum noise voltage ever be completely eliminated?

No, it is not possible to completely eliminate noise voltage in a circuit. However, it can be minimized by using high-quality components, proper shielding and grounding techniques, and proper circuit design.

5. How can the maximum noise voltage be reduced in electronic devices?

The maximum noise voltage can be reduced in electronic devices by using low-noise components, filtering techniques, and proper circuit layout and design. Additionally, using external isolation and grounding techniques can also help reduce noise voltage in electronic devices.
