تجارب المغناطيسية العملية بالصور
السلام عليكم ورحمة الله وبركاته تجارب المغناطيسية العملية بالصور Circles of Magnetism I You can make a magnetic field that's stronger than the earth's! Circles of Magnetism IV Two parallel, current-carrying wires exert forces on each other. Curie Point When a piece of iron gets too hot, it is no longer attracted to a magnet. Diamagnetism A grape is repelled by both the north and south poles of a strong rare-earth magnet. The grape is repelled because it contains water, which is diamagnetic. Diamagnetic materials are repelled by magnetic poles. Eddy Currents A magnet falls more slowly through a ****llic tube than it does through a non****llic tube. Magnetic Lines of Force Iron filings will trace out the lines of a magnetic field in three dimensions. Magnetic Pendulums Copper coils become electromagnetic swings. Magnetic Shielding Explore magnetic shielding, lines of force and the concept of permeabllity with low cost material. Magnetic Suction This experiment shows how your doorbell works. Motor Effect A magnet exerts a force on a current-carrying wire. Strange Attractor The attraction and repulsion of magnets produces entrancing, unpredictable motion. Stripped Down Motor
As motors go, this is about as simple as it gets.
