Its origins are in microwave discharge light sources used for ultraviolet curing in the semiconductor and printing industries. Since 1994, General Electric has produced its induction lamp Genura with an integrated high frequency driver, operating at 2.65 MHz. In 1996, Osram started selling their Endura induction light system, operating at 250 kHz.
Alternating electric current flows through the solenoid on the left, producing a changing magnetic field. This field causes, by electromagnetic induction, an electric current to flow in the wire loop on the right.
In a ferromagnetic core inductor, when the magnetic field approaches the level at which the core saturates, the inductance will begin to change, it will be a function of the current (). Neglecting losses, the energy W {\displaystyle W} stored by an inductor with a current I 0 {\displaystyle I_{0}} passing through it is equal to the amount of ...
In molecular biology, an inducer is a molecule that regulates gene expression. [1] An inducer functions in two ways; namely: By disabling repressors. The gene is expressed because an inducer binds to the repressor. The binding of the inducer to the repressor prevents the repressor from binding to the operator.
Light-emitting diodes (LEDs) produce light (or infrared radiation) by the recombination of electrons and electron holes in a semiconductor, a process called "electroluminescence". The wavelength of the light produced depends on the energy band gap of the semiconductors used.
IPTG is an effective inducer of protein expression in the concentration range of 100 μmol/L to 3.0 mmol/L. Typically, a sterile, filtered 1 mol/L solution of IPTG is added 1:1000 to an exponentially growing bacterial culture, to give a final concentration of 1 mmol/L.
Induction plasma, also called inductively coupled plasma, is a type of high temperature plasma generated by electromagnetic induction, usually coupled with argon gas.The magnetic field induces an electric current within the gas which creates the plasma.
The damping force ensures that the oscillator's response is finite at its resonance frequency. For a time-harmonic driving force which originates from the electric field, Newton's second law can be applied to the electron to obtain the motion of the electron and expressions for the dipole moment, polarization, susceptibility, and dielectric ...
