  2. Inductor - Wikipedia

    en.wikipedia.org/wiki/Inductor

    An inductor, also called a coil, ... The current is the charge per unit time passing through the inductor. Therefore, the rate of work done by the ...

  3. Inductive sensor - Wikipedia

    en.wikipedia.org/wiki/Inductive_sensor

    An inductor develops a magnetic field when an electric current flows through it; alternatively, a current will flow through a circuit containing an inductor when the magnetic field through it changes. This effect can be used to detect metallic objects that interact with a magnetic field.

  4. Electromagnetic induction - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_induction

    Electromagnetic induction has found many applications, including electrical components such as inductors and transformers, and devices such as electric motors and generators. History Faraday's experiment showing induction between coils of wire: The liquid battery (right) provides a current that flows through the small coil (A) , creating a ...

  5. Inductance - Wikipedia

    en.wikipedia.org/wiki/Inductance

    Mutually coupled inductors can equivalently be represented by a T-circuit of inductors as shown. If the coupling is strong and the inductors are of unequal values then the series inductor on the step-down side may take on a negative value. [32] This can be analyzed as a two port network.

  6. Faraday's law of induction - Wikipedia

    en.wikipedia.org/wiki/Faraday's_law_of_induction

    As noted in the previous section, Faraday's law is not guaranteed to work unless the velocity of the abstract curve ∂Σ matches the actual velocity of the material conducting the electricity. [31] The two examples illustrated below show that one often obtains incorrect results when the motion of ∂Σ is divorced from the motion of the ...

  7. Inductive charging - Wikipedia

    en.wikipedia.org/wiki/Inductive_charging

    An increase in high-power inductive charging devices has led to researchers looking into the safety factor of the electromagnetic fields (EMF) put off by larger inductor coils. With the recent interest in the expansion of high power inductive charging with electric cars, an increase in health and safety concerns has arisen.

  8. Induction coil - Wikipedia

    en.wikipedia.org/wiki/Induction_coil

    Antique induction coil used in schools from around 1900, Bremerhaven, Germany. An induction coil or "spark coil" (archaically known as an inductorium or Ruhmkorff coil [1] after Heinrich Rühmkorff) is a type of transformer [2] [3] [4] used to produce high-voltage pulses from a low-voltage direct current (DC) supply.

  9. Induction heating - Wikipedia

    en.wikipedia.org/wiki/Induction_heating

    Component of Stirling radioisotope generator is heated by induction during testing. Induction heating is the process of heating electrically conductive materials, namely metals or semi-conductors, by electromagnetic induction, through heat transfer passing through an inductor that creates an electromagnetic field within the coil to heat up and possibly melt steel, copper, brass, graphite, gold ...
