Set Of Five Coils
Set Of Five CoilsStudent investigations into the relationship between coil turns and voltage are well catered for by this inexpensive range of coils designed to be used with ‘Westminster Kit’ type laminated ‘C’ cores and clips.
Splat The Rat
Splat The RatFun and dramatic demonstration of Lenz’s Law. Interactive and entertaining demonstration of induced currents and magnetic fields. Lenz’s Law can be demonstrated using the standard Eddy Current Tubes whereby a magnet falls through a copper tube at a slower rate than an un-magnetised weight.
Static Cell
Static CellWhen insulating materials rub together, electrons transfer from one to the other and, since the charge cannot be conducted away, the charge is retained on the surface.
Switched Power Supply
Switched Power SupplyA traditional switched power supply which uses established PSU technology to provide a smoothed power supply suitable for all laboratory applications which require a rugged source of emf at either AC or DC.
Switched Psu Mkll
Switched Psu MkllA traditional switched power supply which uses established PSU technology to provide a smoothed power supply suitable for all laboratory applications which require a rugged source of emf at either AC or DC.
An internal mechanism disconnects the output when the voltage setting is changed ensuring that the switch contacts are protected from overload and the unit can be locked at any setting by means of an Allen screw located on the front panel.
Three-phase generator set
Three-phase generator setThis kit serves as a model of an alternator. The kit consists of two parts, an induction unit with three coils and a round magnet, as well as a variable motor unit that rotates the round magnet.
Trans-Ratio
Trans-RatioTrans-Ratio is a fully self-contained transformer system which enables students to investigate turns ratios and efficiency with the minimum of complication.
Transformer C-Core Set
Transformer C-Core SetA high quality, high efficiency double C-Core, supplied with a strong rubber band to hold the two halves together. The core is constructed from laminated sheets of cold-rolled, grain-oriented (CRGO) steel, minimising energy loss and maximising magnetic efficiency. The two halves feature a rectangular cross section with machined ends to guarantee a flush fit for optimal contact when placed together.
Transformer Coils Set
Transformer Coils SetSet of six high quality coils and a laminated iron core
Transformer Core
Transformer CoreThis U-shaped iron core is designed to be used with two coils to form a transformer. The core has laminated iron strips to minimise eddy currents. The cross-bar can be removed to allow the installation of the coils.
Zinc Plate
Zinc PlateA 40 × 40mm zinc plate on a 4mm connector which can replace the top plate of an electroscope.
The plate can be used to show discharge under UV Lighting and the photo-electric effect.
