WebAug 18, 2024 · Magnetism is caused by electrons (the negative particles in atoms that are also electric charges) spinning. The more a group of electrons spin in the same direction, … WebSep 12, 2024 · From Equation 16.4.11, the intensity of the laser beam is I = 1 2cϵ0E2 0. The amplitude of the electric field is therefore E0 = √ 2 cϵ0I = √ 2 (3.00 × 108m / s)(8.85 × 10 − 12F / m)(1.0 × 10 − 3W / m2) = 0.87V / m. The amplitude of the magnetic field can be obtained from: B0 = E0 c = 2.9 × 10 − 9T. Light Bulb Fields
