If the electric field in an EM wave in free space has a peak magnitude of 8.7×10−5V/m, what is the peak magnitude of the magnetic field strength?
Answer:____T
To find the peak magnitude of the magnetic field strength in an electromagnetic (EM) wave, we can make use of the relationship between the electric and magnetic fields in free space.
The relationship is given by:
E = c * B
Where:
E is the magnitude of the electric field
B is the magnitude of the magnetic field
c is the speed of light in a vacuum, which is approximately 3 × 10^8 m/s
In this case, the magnitude of the electric field (E) is given as 8.7 × 10^(-5) V/m. We can now use this equation to solve for the magnitude of the magnetic field (B).
B = E / c
B = (8.7 × 10^(-5) V/m) / (3 × 10^8 m/s)
Calculating this expression will give you the peak magnitude of the magnetic field strength in Tesla (T).
