For Westminster Electromagnetic Kit giving 1 V full wave rectified DC and 1 V / 2 V AC outputs at 8 A max.
The circuit diagram is printed on the top panel which also carries mains switch, light indicator and output sockets for DC and AC With 1.5 meter mains detachable cable.
To demonstrate the characteristics of simple and primary cells.
Consists of a plastic jar with a screw-on plastic rim containing two adjustable brass electrode holders, eight electrodes of different metals and a porous ceramic cup.
With Instructions.
Students can explore how a simple electric motor works by doing a series of investigations.
This St. Louis motor can be adjusted so students can study the effect of voltage and position of the brushes on the commutator.
The motor consists of a two pole DC armature. The brush holder, with two heavy binding post terminals, can be rotated for experiments.
The permanent bar magnets, supported by clamps, can be adjusted to the desired location.
This apparatus requires 4 D cell batteries with holder (not included) or a power supply and two connecting leads (not included).
Apparatus is designed primarily for demonstration of the basic principles of transformers.
It consists of a laminated U-core with laminated I-core, both with 32 x 25 mm cross section to form a closed core of size 102 x 127 mm.
Heavy aluminium alloy stand with removable clamping rods, 2 pole pieces, each 65 x 30 x 25 mm with one end cone shaped, to accept support rod and shading ring.
Poles also have a hole drilled through lengthwise to take a light beam. 300 turns 600 turns 1200 turns 3600 turns 12000 turns
To distinguish between the conductors and insulators.
Kit contains five strips of different material (wood, acrylic, copper brass and aluminium), one lamp and one 9 V battery mounted on plastic base.
