5 ELECTROMAGNET A U-form electromagnet, comprising two copper coils wound onto a u-shaped metal former, with attached armature and two 4mm sockets for electrical connection. Operating voltage 4-6V d.c. Size 120mm x 100mm Cat No. Description Price Per ELM-155-100 Electomagnet 15.87 ea. 6 AC MAGNETIC FIELD COIL A coil, mounted vertically on a base, with 10 turns of insulated copper wire and a diameter of 15 cm. Electrical connection to the coil is via 4 mm sockets, which are mounted on the base. When AC is passed through the coil, an alternating magnetic field is induced, which can be detected using a search coil. Requires an AC power supply which can deliver up to 5 Amps at low voltage (e.g. a Westminster power supply). The current should not exceed 5A. Cat No. Description Price Per ELM-120-100 AC Magnetic Field Coil 52.27 ea. 7 DEMO SOLENOID OHP FIELD PATTERN MODEL The model is mounted on clear, transparent acrylic permitting use on an OHP for classroom demonstration. The integrated 4mm socket terminals allow for electrical supply allowing the magnetic effects in each to be visualized through the use of iron filings or plotting compasses. The solenoid coil about 52 x 125mm (Dia. x L) of 16 SWG enamelled copper wire. Each turn is sufficiently apart and well insulated from the adjacent ones. Cat No. Description Price Per ELM-100-100 Solenoid OHP Field Pattern Model 12.98 ea.
