Question

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?

Answer 1

5.37 N/C

Step-by-step explanation:

Peak value of magnetic field, Bo = 17.9 nT = 17.9 x 10^-9 T

The electromagnetic wave is produced when an oscillating electric and magnetic field interacts each other perpendicularly.

The direction of propagation of electromagnetic wave is perpendicular to both electric and magnetic field.

the relation between the electric field and magnetic field amplitudes is given by

`c = (E_(0))/(B_(0))`

where, c be the velocity of light, Eo be the peak value of electric field strength, Bo is the peak value of magnetic field strength.

`3* 10^(8) = (E_(0))/(17.9* 10^(-9))}`

Eo = 5.37 N/C
