Question
The wire in Figure below is being moved downwards through the magnetic field so as to produce induced current.
(a) moving the wire at a higher speed?
(b) moving the wire upwards rather than downwards?
(c) using a stronger magnet?
(d) holding the wire still in the magnetic field?
(e) moving the wire parallel to the magnetic field lines?
Solution
(a) If the wire is moved at a higher speed, the flow of current will increase.
(b) If the wire is moved upwards rather than downwards, the flow of current will reverse.
(c) If we use a stronger magnet, the flow of current will increase.
(d) If the wire is held still in the magnetic field, the flow of current will be zero.
(e) If the wire is moved parallel to magnetic field lines, the flow of current will be zero.
