An electromagnetic wave is propagating in vacuum along the z-direction. The electric field is oscillating with amplitude E₀ = 30 V/m along the x-direction. The amplitude of the magnetic field (in Tesla) is approximately:
Q2 · Electromagnetic Waves · EASY
An electromagnetic wave propagates in vacuum with electric field amplitude E₀ = 6 × 10² V/m. The magnitude of the magnetic field amplitude B₀ (in Tesla) is:
Q3 · Electromagnetic Waves · EASY
The electric field component of an electromagnetic wave in vacuum is given by E = 40 sin(kx - ωt) V/m. The magnitude of the magnetic field component (in T) is approximately: (Given: c = 3 × 10⁸ m/s)
