NettetFaraday’s Law tells us that inducing a voltage into a conductor can be done by either passing it through a magnetic field, or by moving the magnetic field past the conductor and that if this conductor is part of a closed circuit, an electric current will flow. NettetFigure 10.3.1 (a) Magnetic flux changes as a loop moves into a magnetic field; (b) magnetic flux changes as a loop rotates in a magnetic field. It’s interesting to note that what we perceive as the cause of a particular flux change actually depends on the frame of reference we choose. NettetThe magnetic field arises when a charge is in motion. There are two basic ways to arrange for a charge to be in motion and generate a useful magnetic field. Following are the two ways: Magnetic Field created by a Current-Carrying Conductor Ampere suggested that a magnetic field is produced whenever an electrical charge is in motion. orchids qatar
