Electricity and magnetism
Adjustable Magnet
Adjustable MagnetConsisting of a steel frame with lockable, adjustable jaws which will accept 50 x 20mm ferrite slab magnets or neodymium button magnets. The field strength can be changed by adjusting the distance.
Aluminium Foil Support Bar
Aluminium Foil Support BarA neat and effective way of supporting foil strips when demonstrating the attraction and repulsion of current carrying conductors.
B.I.L. COIL
B.I.L. COILA printed circuit board coil on support handle with 5 and 10 turns rated at 2A. The lower arm of the coil is 75mm long (minimum) and 20mm wide.
Bridge Rectifier System
Bridge Rectifier SystemA must for the effective demonstration of this important circuit.
This unit contains a bridge rectifier circuit with LEDs showing which diodes are conducting during each half cycle of the a.c. supply.
Capacitance Box
Capacitance BoxThe Capacitance Box has ten capacitance values in a plastic enclosure measuring 185 x 80 x 65mm.
Capacitance Selector
Capacitance SelectorTwelve non-electrolytic capacitors selected by a rotary switch mounted on an acrylic base.
Capacitor Investigation
Capacitor InvestigationThis apparatus provides a self-contained unit to enable students to study the charge and discharge characteristics of a capacitor.
Circuit Breaker
Circuit BreakerThis unit will prove invaluable for showing applications of electromagnetic devices (the solenoid) and bi-metal strips as well as bringing them all together to demonstrate the key principles of the modern domestic circuit breaker.

Decade Resistance Box
Decade Resistance BoxA four decade resistance box covering 1Ω to 9999Ω in 1Ω steps. Resistors are 1% tolerance. Max current 0.35A. Power rating 1W continuous. 4mm sockets allow the unit to be used as a potential divider.
Demonstration Electric Motor
Demonstration Electric MotorThe Demonstration Electric Motor is a ready built fully functional unit showing all the essential features of a simple motor as taught in the KS4 syllabus. A single rectangular coil rotates in a linear magnetic field with a simple commutator and brush arrangement. Field directions can be reversed by reversing the ferrite slab magnets and current direction can be reversed by reversing the leads. Requires DC voltage in the range 1.5 V – 6 V.
