How to Calculate RMS Magnetic Field Strength from Sunlight Power Density?

In summary, to calculate the rms magnetic field strength, we can use the equation S = E(rms)^2 = √(εμ), substituting B(rms)/c for E(rms) and solving for B(rms). However, this may not give the correct solution and further calculations or adjustments may be necessary.

The Attempt at a Solution


I tried using the equation for power density S = E(rms)^2=√(εμ), then substituting B(rms)/c for E(rms), and subsequently solving for B(rms). However this does not give me the correct solution and I am now confused

Related to How to Calculate RMS Magnetic Field Strength from Sunlight Power Density?

What is Rms magnetic field strength?

Rms (root-mean-square) magnetic field strength is a measure of the average strength of a magnetic field over a given time period. It takes into account both the amplitude and duration of the magnetic field.

How is Rms magnetic field strength calculated?

Rms magnetic field strength is calculated by squaring the values of the magnetic field at each point in time, averaging these values, and then taking the square root of the result. This calculation is performed for a specific time period, such as one second.

What are the units of measurement for Rms magnetic field strength?

The units of measurement for Rms magnetic field strength are typically given in Tesla (T) or Gauss (G). These units measure the strength of a magnetic field in a given direction.

Why is Rms magnetic field strength important?

Rms magnetic field strength is important because it allows us to quantify the strength of a magnetic field over time. This is useful in many scientific and engineering applications, such as in the design and testing of magnetic devices and equipment.

How is Rms magnetic field strength different from peak magnetic field strength?

Rms magnetic field strength and peak magnetic field strength are two different measures of magnetic field strength. Rms takes into account the duration of the magnetic field, while peak measures the maximum strength of the field at any given point in time. Rms is often considered a more accurate measure of the overall strength of a magnetic field, while peak is useful for identifying the maximum strength that a device or material can withstand.
