Spintronics devices: Spintronics are mostly used in storage and memory devices. They have the capability of storing huge quantity of information and can be used as a storage device like hard disk and so on. The procedure employed by the spintronics devices to store data are systematic and structured. Originally‚ the spin of the electron is utilized to accumulate and write the data in a specific direction (spin “upward” or spin “downward”). Then‚ the spin of other left out moving electron particles

year 1775‚ animal gravitation was created and revised by the genius himself. This theory was compared to that of animal magnetism. Animal magnetism allowed fluid not able to be seen inside the human act as magnets.His thought was that the tidal influences of all 9 universes can operate in a force that relates to the forcer of the galaxy. In the eyes of Mesmer’s body‚animal magnetism could be started by any object that is magnetizable and triggered by a person that is trained. The mastermind invented

An iodine test was used to indicate whether corn starch or baby powder was contained in the mixture because it is an indicator. An indicator is a substance that undergoes a distinct observable change when conditions in its solution change (Indicator). A flame test was used to determine whether copper or strontium was contained in the

Albert Einstein in 1905; and from this it was shown that magnetic fields and electric fields are convertible with relative motion as a four vector and this led to their unification as electromagnetism.

As he was setting up his materials‚ he noticed a compass needle deflected from magnetic north when the electric

Mesmer chose his term to clearly distinguish his variant of magnetic force from those referred to at the time as mineral magnetism‚ cosmic magnetism and planetary magnetism. Mesmer felt that this particular force/power only resided in the bodies of humans and animals. Mesmer chose the word "animal‚" for its root meaning (from

through them because of these free electrons. Electricity needs these conductive materials to move from place to place and to get electricity to move requires an electrical generator. There is a link between electricity and magnetism. Electricity can produce magnetism and magnetism can produce electricity. This is why generators use magnets to get electricity moving. A magnet spins inside a coil of wire to get those free electrons moving around thus creating electricity. Generators can be very small

Evidence of the rapid decline of the Earth’s magnetism is proven in pottery‚ when the clay is fired in the kiln small pieces of magnetite in the clay align magnetism with the Earth’s magnetic field at the time. Experiments have revealed that what could cause the end of our living planet is when the Earth’s core becomes too cold to maintain the magnetism that it currently has. Scientists have made a startling discovery though; evidence shows that
