MAGNETIC FIELD DEMONSTRATOR EISCO |
|
The demonstrator comprises a set of two transparent plastic
plates 153 x 76 x 6 mm., each plate has a matrix of 98 (14 x 7)
small circular chambers, each chamber containing an iron rod

be arranged in various ways, e.g. as a single large two
dimensional surface, as faces of a cube etc., and in this way may
be used to show configuration of a magnetic field in one or two
dimensions. The transparent nature of the plates also makes
them suitable for use on an overhead projector. |

|
Demonstrate the construction and operation principle behind AC
and DC generators. Turning of the hand wheel lights up the
bulb. The generator is a permanent magnet rotating armature
generator. When the two brushes of the generator are put in the
two ends of the commutator, the output given is of alternating
current (A.C.) and when the brushes are put in the middle of
the commutator, the output is of direct current (D.C.). |
