If the magnetic field in a traveling EM wave has a peak value of 17.9nT, what is the peak value of the electric field strength?
To find the peak value of the electric field strength, we need to use the relationship between the electric field strength (E) and the magnetic field strength (B) in an electromagnetic (EM) wave. This relationship is given by the equation:
E = c * B
Where:
E is the electric field strength
B is the magnetic field strength
c is the speed of light in a vacuum (approximately 3.0 x 10^8 meters per second)
Given that the magnetic field strength (B) has a peak value of 17.9 nT (nanoTesla), we can convert it to Tesla by dividing it by 10^9:
B = 17.9 nT = 17.9 * 10^(-9) T
Now, we can calculate the peak value of the electric field strength by multiplying the magnetic field strength by the speed of light:
E = c * B
E = (3.0 x 10^8 m/s) * (17.9 * 10^(-9) T)
Calculating this expression gives us the peak value of the electric field strength.
