  1. Magnetic flux and Faraday's law (article) | Khan Academy

    Learn what magnetic flux is, how to calculate it, and how it relates to Faraday's law.

  2. Flux and magnetic flux (video) | Khan Academy

    But what do we mean by magnetic, by magnetic flux? Well, like regular flux, we're still dealing with how things are kind of, you could say going through a surface.

  3. What is Faraday's law? (article) | Khan Academy

    Faraday's law, due to 19ᵗʰ century physicist Michael Faraday. This relates the rate of change of magnetic flux through a loop to the magnitude of the electro-motive force E ‍ induced in the loop. The …

  4. Lenz's law (video) | Khan Academy

    When the magnetic flux through a conducting loop changes, current is induced in the loop. This current produces it's own magnetic field. Lenz's law tells us that the current flows in the direction that …

  5. Magnetic flux and Faraday's law (article) | Khan Academy

    Magnetic flux is a measure of the quantity of magnetism, considering the strength and extent of a magnetic field.

  6. Khan Academy

    Khan Academy ... Khan Academy

  7. What are magnetic fields? (article) | Khan Academy

    The magnetic field of the Earth arises from moving iron in the Earth's core. The poles of the Earth's magnetic field are not necessarily aligned to the geographic poles.

  8. Electromagnetic induction (video) | Khan Academy

    When it comes to inducing electromotive force (EMF), a change in magnetic flux is the key player. To achieve this, there has to be a shift in the number of magnetic field lines passing through a given …

  9. Emf induced in rod traveling through magnetic field

    An emf induced by motion relative to a magnetic field is called a motional emf. This is represented by the equation emf = LvB, where L is length of the object moving at speed v relative to the strength of the …

  10. Faraday's Law example (video) | Khan Academy

    With each current, at one point, it creates magnetic field in the direction of magnetic flux and opposite direction of magnetic flux. If someone could explain this, it would be great.
