  2. Electromagnetic induction - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_induction

    Electromagnetic or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction .

  3. Eddy-current testing - Wikipedia

    en.wikipedia.org/wiki/Eddy-current_testing

    Visualization of Eddy Currents Induction [3] In its most basic form — the single-element ECT probe — a coil of conductive wire is excited with an alternating electric current. This wire coil produces an alternating magnetic field around itself. The magnetic field oscillates at the same frequency as the current running through the coil.

  4. Faraday's law of induction - Wikipedia

    en.wikipedia.org/wiki/Faraday's_law_of_induction

    This field causes, by electromagnetic induction, an electric current to flow in the wire loop on the right. The most widespread version of Faraday's law states: The electromotive force around a closed path is equal to the negative of the time rate of change of the magnetic flux enclosed by the path.

  5. Eddy current - Wikipedia

    en.wikipedia.org/wiki/Eddy_current

    Eddy currents in conductors of non-zero resistivity generate heat as well as electromagnetic forces. The heat can be used for induction heating. The electromagnetic forces can be used for levitation, creating movement, or to give a strong braking effect. Eddy currents can also have undesirable effects, for instance power loss in transformers.

  7. Oersted's law - Wikipedia

    en.wikipedia.org/wiki/Oersted's_law

    Ørsted investigated and found the physical law describing the magnetic field, now known as Ørsted's law. Ørsted's discovery was the first connection found between electricity and magnetism, and the first of two laws that link the two; the other is Faraday's law of induction.

    Boise State should be getting a first-round bye in the College Football Playoff. The No. 10 Broncos put No. 20 UNLV away in the first half on the way to a 21-7 win in the Mountain West Conference ...

  9. AP Physics - Wikipedia

    en.wikipedia.org/wiki/AP_Physics

    Both exams have the same number of multiple-choice questions and have identical free-response formats. [2] AP Physics 1 has the lowest average exam scores of any AP exam, while AP Physics C: Mechanics has among the highest. [3] Both exams cover a similar mixture of topics, focusing primarily on Newtonian mechanics, kinematics, rotation, and ...
