  2. Flux linkage - Wikipedia

    en.wikipedia.org/wiki/Flux_linkage

    In circuit theory, flux linkage is a property of a two-terminal element. It is an extension rather than an equivalent of magnetic flux and is defined as a time integral [citation needed] where is the voltage across the device, or the potential difference between the two terminals. This definition can also be written in differential form as a rate.

  3. Weber (unit) - Wikipedia

    en.wikipedia.org/wiki/Weber_(unit)

    1 × 108 Mx. In physics, the weber (/ ˈveɪb -, ˈwɛb.ər / VAY-, WEH-bər; [1][2] symbol: Wb) is the unit of magnetic flux in the International System of Units (SI). The unit is derived (through Faraday's law of induction) from the relationship 1 Wb = 1 V⋅s (volt-second). A magnetic flux density of 1 Wb/m 2 (one weber per square metre) is ...

  4. Coenergy - Wikipedia

    en.wikipedia.org/wiki/Coenergy

    In physics and engineering, Coenergy (or co-energy) is a non-physical quantity, measured in energy units, used in theoretical analysis of energy in physical systems. [1] The concept of co-energy can be applied to many conservative systems (inertial mechanical, electromagnetic, etc.), which can be described by a linear relationship between the ...

  5. Flux - Wikipedia

    en.wikipedia.org/wiki/Flux

    Flux as flow rate per unit area. In transport phenomena (heat transfer, mass transfer and fluid dynamics), flux is defined as the rate of flow of a property per unit area, which has the dimensions [quantity]· [time] −1 · [area] −1. [6] The area is of the surface the property is flowing "through" or "across".

  6. Inductance - Wikipedia

    en.wikipedia.org/wiki/Inductance

    Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. The electric current produces a magnetic field around the conductor. The magnetic field strength depends on the magnitude of the electric current, and follows any changes in the magnitude of the current.

  7. Henry (unit) - Wikipedia

    en.wikipedia.org/wiki/Henry_(unit)

    The henry (symbol: H) is the unit of electrical inductance in the International System of Units (SI). [1] If a current of 1 ampere flowing through a coil produces flux linkage of 1 weber turn, that coil has a self-inductance of 1 henry.‌ The unit is named after Joseph Henry (1797–1878), the American scientist who discovered electromagnetic induction independently of and at about the same ...

  8. Faraday paradox - Wikipedia

    en.wikipedia.org/wiki/Faraday_paradox

    Faraday paradox. The Faraday paradox or Faraday's paradox is any experiment in which Michael Faraday 's law of electromagnetic induction appears to predict an incorrect result. The paradoxes fall into two classes: Faraday's law appears to predict that there will be zero electromotive force (EMF) but there is a non-zero EMF. Faraday's law ...

  9. Energy release rate (fracture mechanics) - Wikipedia

    en.wikipedia.org/wiki/Energy_release_rate...

    The energy release rate is defined [3] as the instantaneous loss of total potential energy per unit crack growth area , where the total potential energy is written in terms of the total strain energy , surface traction , displacement , and body force by. The first integral is over the surface of the material, and the second is over its volume .
