  2. FBI mnemonics - Wikipedia

    en.wikipedia.org/wiki/FBI_mnemonics

    The various FBI mnemonics (for electric motors) show the direction of the force on a conductor carrying a current in a magnetic field as predicted by Fleming's left hand rule for motors [1] and Faraday's law of induction. Other mnemonics exist that use a right hand rule for predicting resulting motion from a preexisting current and field.

  3. Faraday's law of induction - Wikipedia

    en.wikipedia.org/wiki/Faraday's_law_of_induction

    Faraday's law of induction (or simply Faraday's law) is a law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (emf). This phenomenon, known as electromagnetic induction , is the fundamental operating principle of transformers , inductors , and many types of electric ...

  4. Fleming's right-hand rule - Wikipedia

    en.wikipedia.org/wiki/Fleming's_right-hand_rule

    There is also a Fleming's left-hand rule (for electric motors). The appropriately handed rule can be recalled from the letter "g", which is in "right" and "generator". These mnemonics are named after British engineer John Ambrose Fleming, who invented them. An equivalent version of Fleming's right-hand rule is the left-hand palm rule. [2]

  5. Electromagnetic induction - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_induction

    Electromagnetic induction was discovered by Michael Faraday, published in 1831. [3] [4] It was discovered independently by Joseph Henry in 1832. [5] [6] In Faraday's first experimental demonstration (August 29, 1831), he wrapped two wires around opposite sides of an iron ring or "torus" (an arrangement similar to a modern toroidal transformer).

    1 Faraday's law compared to the Maxwell–Faraday equation. ... is outward toward the rim according to the right-hand rule. Of course, this radial force, which is the ...

  7. Right-hand rule - Wikipedia

    en.wikipedia.org/wiki/Right-hand_rule

    In mathematics and physics, the right-hand rule is a convention and a mnemonic, utilized to define the orientation of axes in three-dimensional space and to determine the direction of the cross product of two vectors, as well as to establish the direction of the force on a current-carrying conductor in a magnetic field.

  8. Electrostatic induction - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_induction

    The two rules of induction are: [5] [6] If the object is not grounded, the nearby charge will induce equal and opposite charges in the object. If any part of the object is momentarily grounded while the inducing charge is near, a charge opposite in polarity to the inducing charge will be attracted from ground into the object, and it will be ...

  9. Proximity effect (electromagnetism) - Wikipedia

    en.wikipedia.org/wiki/Proximity_effect...

    From the right hand rule the field lines pass through the wire in an upward direction. From Faraday's law of induction , when the time-varying magnetic field is increasing, it creates a circular current (E, red loops) within the wire around the magnetic field lines in a clockwise direction.
