The new version of TecTile, called TecTile 2, have improved compatibility, [10] but currently the Samsung Galaxy S4 is the only device that comes with native support for TecTile 2. [ 11 ] NFC Tags that do comply with NFC Forum Type 1 or Type 2 compatibility protocols [ 12 ] are much more widely compatible than the MIFARE dependant Samsung ...
In physics, specifically electromagnetism, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface. It is usually denoted Φ or Φ B. The SI unit of magnetic flux is the weber (Wb; in derived units, volt–seconds or V⋅s), and the CGS unit is the maxwell. [1]
The official planetary K p-index is derived by calculating a weighted average of K-indices from a network of 13 geomagnetic observatories at mid-latitude locations.Since these observatories do not report their data in real-time, various operations centers around the globe estimate the index based on data available from their local network of observatories.
Fig. 1. Illustration of the frozen mirror image method for a simplest case of the magnetic dipole over the flat superconducting surface. Frozen mirror image method (or method of frozen images) is an extension of the method of images for magnet-superconductor systems that has been introduced by Alexander Kordyuk in 1998 to take into account the magnetic flux pinning phenomenon.

For an electromagnet with a cylindrical bore, producing a pure multipole field of order , the stored magnetic energy is: =!. Here, is the permeability of free space, is the effective length of the magnet (the length of the magnet, including the fringing fields), is the number of turns in one of the coils (such that the entire device has turns), and is the current flowing in the coils.
The magnetic flux distribution of a linear Halbach array may seem somewhat counter-intuitive to those familiar with simple magnets or solenoids. The reason for this flux distribution can be visualised using Mallinson's original diagram (note that it uses the negative y component, unlike the diagram in Mallinson's article). [ 4 ]
Samsung is recalling more than 1.1 million electric ranges sold nationwide after the products were linked with roughly 250 fires, leading to dozens of injuries and killing at least seven pets.
Working of the undulator. 1: magnets, 2: electron beam entering from the upper left, 3: synchrotron radiation exiting to the lower right. An undulator is an insertion device from high-energy physics and usually part of a larger installation, a synchrotron storage ring, or it may be a component of a free electron laser.
