Fleming's right-hand rule
Fleming proposed a simple rule for giving
the direction of the induced current to explain one of Faraday's experiments as follows:


Faraday's
and Lenz's laws may be tested by the following simple experiments:
(a) rotating a
metal disc at a constant rate in a magnetic field and measuring the e.m.f. generated between
the rim and the axle;
(b) moving a bar magnet within a solenoid connected to a
meter;
(c) rotating a magnet near a coil connected to a cathode ray
oscilloscope.
