Photoacoustic Doppler effect

The photoacoustic Doppler effect is one specific kind of Doppler effect, which occurs when an intensity modulated light wave induces a photoacoustic wave ... more

Runoff curve number

Surface runoff is the water flow that occurs when the soil is infiltrated to full capacity and excess water from rain. The runoff curve number (also called ... more

Hall parameter (due to Hall effect in ionized gases)

The Hall parameter, β, in a plasma is the ratio between the electron gyro-frequency, and the electron-heavy particle collision frequency. In a plasma, the ... more

Magnetic Prandtl number (with Reynolds number)

The Magnetic Prandtl number is a dimensionless quantity occurring in magnetohydrodynamics which approximates the ratio of momentum diffusivity (viscosity) ... more

Tunnel Ionization - DC

Tunnel ionization is a process in which electrons in an atom (or a molecule) pass through the potential barrier and escape from the atom (or molecule). In ... more

Torque on a dipole (magnetic field)

A physical dipole consists of two equal and opposite point charges. When placed in an magnetic field, equal but opposite forces arise on each side of the ... more

Magnetic Prandtl number (diffusion rate)

The Magnetic Prandtl number is a dimensionless quantity occurring in magnetohydrodynamics which approximates the ratio of momentum diffusivity (viscosity) ... more

Torque on a current-carring loop

When current is passed through the loops, the magnetic field exerts torque on the loops, which rotates a shaft. Electrical energy is converted to ... more

Brushed DC electric motor - Speed

A brushed DC motor is an internally commutated electric motor designed to be run from a direct current power source. Brushed motors were the first ... more

Magnetic force (between parallel conductors)

In magnetostatics, the force of attraction or repulsion between two current-carrying wires is often called Ampère’s force law. The ... more
