  2. iPhone 15 Pro - Wikipedia

    en.wikipedia.org/wiki/IPhone_15_Pro

    The iPhone 15 Pro and Pro Max support AV1 video hardware decoding. [14] In iOS 18, the iPhone 15 Pro and Pro Max are the first iPhones to be capable of supporting the new Apple Intelligence AI features, due to the increased amount of DRAM in these models and their fast 35 trillion-operation-per-second Neural Engine.

  3. Skin effect - Wikipedia

    en.wikipedia.org/wiki/Skin_effect

    The back EMF is strongest / most concentrated at the center of the conductor, allowing current only near the outside skin of the conductor, as shown in the diagram on the right. [ 2 ] [ 3 ] Regardless of the driving force, the current density is found to be greatest at the conductor's surface, with a reduced magnitude deeper in the conductor.

  4. EMF measurement - Wikipedia

    en.wikipedia.org/wiki/EMF_measurement

    An EMF meter is a scientific instrument for measuring electromagnetic fields (abbreviated as EMF). Most meters measure the electromagnetic radiation flux density (DC fields) or the change in an electromagnetic field over time (AC fields), essentially the same as a radio antenna, but with quite different detection characteristics.

    en.wikipedia.org/wiki/IPhone_14_Pro

    This new feature is on the new iPhone 15 series (iPhone 15, iPhone 15 Plus, iPhone 15 Pro, iPhone 15 Pro Max). The iPhone 14 Pro and 14 Pro Max are available in four colors: Silver, Space Black, Gold and Deep Purple. Deep Purple replaced the Sierra Blue color used on the iPhone 13 Pro and iPhone 13 Pro Max. It is the final iPhone model in the ...

  6. Electromagnetic shielding - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_shielding

    In electrical engineering, electromagnetic shielding is the practice of reducing or redirecting the electromagnetic field (EMF) in a space with barriers made of conductive or magnetic materials. It is typically applied to enclosures, for isolating electrical devices from their surroundings, and to cables to isolate wires from the environment ...

  7. Eddy current - Wikipedia

    en.wikipedia.org/wiki/Eddy_current

    This change in magnetic flux, in turn, induces a circular electromotive force (EMF) in the sheet, in accordance with Faraday's law of induction, exerting a force on the electrons in the sheet, causing a counterclockwise circular current in the sheet. This is an eddy current.

    Apple A16 Bionic (iPhone 14 Pro, iPhone 14 Pro Max, iPhone 15, iPhone 15 Plus), Apple A18 ( iPhone 16e ) The Apple A15 Bionic is a 64-bit ARM-based system on a chip (SoC) designed by Apple Inc. , part of the Apple silicon series.

  9. Penetration depth - Wikipedia

    en.wikipedia.org/wiki/Penetration_depth

    Penetration depth is a measure of how deep light or any electromagnetic radiation can penetrate into a material. It is defined as the depth at which the intensity of the radiation inside the material falls to 1/ e (about 37%) of its original value at (or more properly, just beneath) the surface.
