If a magnet moves towards a closed loop, then the induced current in the loop creates a field that exerts a force opposing the motion of the magnet. Lenz's law can be derived from Faraday's law of induction by noting the negative sign on the right side of the equation.
The Horse in Motion: June 1878 Eadweard Muybridge: Palo Alto, California, United States Composite from multiple glass plates Series of cabinet cards regarded as a precursor to motion pictures. Pictured left is the variant Sallie Gardner at a Gallop, which further captured a horse's motion. [s 2] [s 3] [s 4]
The photographs were most likely never intended to be presented as motion pictures, but much later images of one disc were transferred and animated into a very short stop motion film. [26] In 1875 and 1876, Janssen suggested that the revolver could also be used to document animal locomotion , especially that of birds, since they would be hard ...
The detection of magnetic monopoles is an open problem in experimental physics. In some theoretical models, magnetic monopoles are unlikely to be observed, because they are too massive to be created in particle accelerators, and also too rare in the Universe to enter a particle detector with much probability.
There were earlier cinematographic screenings by others like the first showing of life sized pictures in motion 1884 in Berlin by Ottomar Anschütz; however, the commercial, public screening of ten Lumière brothers' short films in Paris on 28 December 1895, can be regarded as the breakthrough of projected cinematographic motion pictures. The ...

1902 – Arthur Korn devises practical telephotography technology (reduction of photographic images to signals that can be transmitted by wire to other locations).Wire-Photos are in wide use in Europe by 1910, and transmitted to other continents by 1922. 1907 – The Autochrome plate is introduced. It becomes the first commercially successful ...
View from the Window at Le Gras 1826 or 1827, believed to be the earliest surviving camera photograph. [1] Original (left) and colorized reoriented enhancement (right).. The history of photography began with the discovery of two critical principles: The first is camera obscura image projection; the second is the discovery that some substances are visibly altered by exposure to light.
