Electricity and magnetism
A.C. Generator
A.C. GeneratorThis apparatus is designed to enable students to investigate the properties of an a.c. generator as used in a bicycle dynamo. A permanent magnet rotates inside a coil of wire. As the field through the coil changes a current is induced in the coil and this is brought out to two 4mm sockets.
A.C. Waveform Demonstrator
A.C. Waveform DemonstratorA unique teaching aid for the concept of alternating current. When a 12V d.c. supply is connected to the input the output can be varied from +6V to -6V under manual control.
ADC Analogue to Digital Converter
ADC Analogue to Digital ConverterThis unit is designed to assist in the understanding of digital and analogue communications systems. When a variable voltage is applied to the input terminals it is converted into a digital output.
ADC/DAC System
ADC/DAC SystemThis instrument combines the functions of the separate ADC and DAC in one compact and simple to use system. There are no adjustments required and there is no access to the intermediate binary values.
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 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.
DAC Digital to Analogue Converter
DAC Digital to Analogue ConverterThis is a companion unit to the ADC which converts a digital input in the range 0 to binary 111 into an analogue voltage output. Binary 111 gives 7 volts.
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.

E-Field Detector
E-Field DetectorThe Lascells E-Field Detector provides a new and novel way to demonstrate charge. This highly sensitive electronic device is an essential piece of equipment in the Physics teachers’ armoury as it can detect very small charges and their polarity, as well as charge at a distance.
Earth Neutral Live Demo
Earth Neutral Live DemoThis apparatus is an effective demonstration of how the earth wire and fuse act together to protect both the user and the appliance.
