1 WESTMINSTER MOTOR KIT Contains enough components to construct six motors. Kit comprises: 12 x Anisotropic Ceramic Ferrite Magnets, 6 x Armatures, 6 x Mild Steel Yokes, 6 x Support Bases, 6 x Shafts, 24 x Rivets, 12 x Split Pins, 1 x Reel Insulated Copper Wire, 1 x Insulated Tubing (2.5mm Bore 30cm long), 2 x Sellotape Rolls Cat No. Description Price Per ELM-400-100 Westminster Motor Kit 62.98 ea. ELM-350-050 Spare Armatures 9.98 5pk ELM-350-070 Spare Bases 7.70 5pk ELM-350-090 Spare Rivets 7.35 50pk ELM-350-110 Spare Shaft 6.50 10 ELM-350-130 Spare Split Pins 1.95 10pk ELM-350-150 Spare Tubing 2.90 100cm ELM-350-170 Spare Yokes 8.50 5pk 2 VOLT E-M WESTMINSTER POWER SUPPLY A Westminster type power supply, specifically designed for electromagnetic experiments which require high currents at low voltage. The unit outputs 2.5V a.c. / 1.5V d.c. at up to 16A a.c. or d.c. current. Output is via 4mm sockets, which accept standard 4mm plugs, shrouded plugs or spring loaded shrouded plugs. The unit is totally short circuit proof – the transformer is specially designed to withstand prolonged short circuits - and is constructed of powder coated Zintec steel. Mains power input is via an integral IEC connector, with mains fuse, an on/ off switch and inclusive lead. 4 of these units will fit into a Gratnells tray. Cat No. Description Price Per POW-540-100 Volt E-M Westminster Power Supply 106.90 ea. 3 LASCELLS FARADAY’S LAW APPARATUS This system provides a simple and effective method of studying Faraday’s Law. An acrylic tube supports an easily moved coil so that a small cylindrical magnet (supplied) can be dropped down the tube to generate a pulse of electricity as it passes through. An oscilloscope is used to monitor the pulse and measure its amplitude. At different speeds the amplitude varies and can be used by senior students to investigate Faraday’s Law while revising equations of motion to determine the speed. PC based oscilloscopes are particularly suited to this equipment and full instructions are included. Twin coils, 150 and 300 turns, allows for extra versatility. KS4/Post-16. Cat No. Description Price Per ELM-515-100 Faraday’s Law Apparatus 39.60 ea. 4 LASCELLS JOULE GUN This highly original apparatus offers an exciting application of topics such as energy storage, capacitor charging, mechanical energy, efficiency and electromagnetism. The control box provides five high value capacitors which can be switched into the charge circuit as required. When the FIRE button is pressed the energy stored is released as a pulse into a low resistance coil to fire a small steel projectile. Variables include, voltage, time, capacity, distance, kinetic and potential energy. Applicable to many topics at GCSE and Post-16. Ships with a 15 page experiment booklet. Cat No. Description Price Per ELM-585-100 Joule Gun 181.92 ea. 5 LASCELLS B.I.L. COIL A 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. In use the coil is supported between the poles of 2 ferrite slab magnets on a yoke or in the adjustable magnet on the top pan of an electronic balance. When a current is passed through the coil the force can be easily measured by the change in reading on the balance and investigations into F=BIL can be carried out. Cat No. Description Price Per ELM-595-100 B.I.L. Coil 27.50 ea.
