If you turn the blade on an electric fan with your finger, then you have made it into an electric generator. . I often demonstrate this fact in class with hand-held electric generators. Static magnetic fields in materials such as ironare more-or-less caused by the motion of electrons within atoms. But if the magnet is held still inside the loop, nothing will happen. . When current is passed through the wire, the compass will deflect, indicating the presence of a magnetic field circling the wire. . Who can have Debit Card? Both this and the field shown in the previous illustration are called dipole fields, because they are created by two poles. Do not reveal the PIN number to any body. Probably the most puzzling result was the now-famous Michelson-Morley experiment of 1887. . A debit card will allow the customer for purchase through POS / E-commerce and withdraw Cash from any ATMs in India and abroad. According to Maxwell, it seemed that they ought. What should customer do on receipt of debit card? It gradually became clear to a number of people that Maxwell's equations predicted that electromagnetic waves should always be produced any time you had electric charges under acceleration. . Debit Card will be activated for use at POS only after it is used at ATM. Whether the Earth was moving in the same direction as the light in their experiment, or opposite to it, or at right angles to it, the result was always the same: the speed of light that they measured never varied. .
