In nonlinear systems, the three-wave equations, sometimes called the three-wave resonant interaction equations or triad resonances, describe small-amplitude waves in a variety of non-linear media, including electrical circuits and non-linear optics. They are a set of completely integrable nonlinear partial differential equations.
The maximum output of Type I tape at 40 Hz is 3–5 dB lower than MOL 400, [14] while in Type IV tapes it is 6–7 dB lower. [15] As a result, ferric tapes handle bass-heavy music with apparent ease compared to expensive metal tapes.
This page lists examples of magnetic induction B in teslas and gauss produced by various sources, grouped by orders of magnitude.. The magnetic flux density does not measure how strong a magnetic field is, but only how strong the magnetic flux is in a given point or at a given distance (usually right above the magnet's surface).
3.2 × 10 −5 T (31.869 μT) – strength of Earth's magnetic field at 0° latitude, 0° longitude; 4 × 10 −5 T (40 μT) – walking under a high-voltage power line [9] 5 × 10 −3 T (5 mT) – the strength of a typical refrigerator magnet; 0.3 T – the strength of solar sunspots; 1 T to 2.4 T – coil gap of a typical loudspeaker magnet
