SUMMARY
The discussion focuses on calculating the amplitude of the magnetic field of an electromagnetic wave with an intensity of 80 MW/m². The relevant constants include the speed of light (c = 3.0 x 10⁸ m/s), permeability of free space (μ₀ = 4π × 10⁻⁷ T ∙ m/A), and permittivity of free space (ε₀ = 8.85 × 10⁻¹² C²/N ∙ m²). The initial calculation attempted to use the formula E₀ = √(2N(√(μ₀/ε₀)), but the user expressed uncertainty about relating electrical amplitude to magnetic amplitude. Accurate calculations require a clear understanding of the relationship between electric and magnetic fields in electromagnetic waves.
