SUMMARY
The magnetic field amplitude of an electromagnetic wave can be calculated using the equation E₀ = B₀ * c, where E₀ is the electric field amplitude, B₀ is the magnetic field amplitude, and c is the speed of light (approximately 3 x 10^8 m/s). Given an electric field amplitude of 100 V/m, the correct calculation yields a magnetic field amplitude of approximately 3.33 x 10^-7 T (Tesla). The initial attempt of 0.0000003 T is incorrect due to a miscalculation in expressing the result as a decimal.
