Van de Graff generator HG0008
• set includes: a conical and a spherical conductor with a spike and a stand, a spherical conductor with an insulated handle, an electrostatic mill, a brush • manual drive • size: H 74 cm, dome ø 26,5 cm
Lenz’s Law HG0095
The model consists of two metal loops fixed to the opposite ends of an aluminium bar which can move freely on a pin. One loop is complete, the other one split. When the magnetic flux changes, according to Lenz’s law current is induced in the complete loop to oppose the change. • size: 20,3 x 15,2 x 7,6 cm
ELECTROSTATICS
Wimshurst machine BZ8002 • creates lightning 6 cm long; • dim of the base: 29 x 18 cm, H 34 cm
Electromagnet QH2411
The electromagnet consists of a coil of wire wrapped around a ferromagnetic core in an open magnetic circuit. On the outer layer there are a few rubber coils to indicate the winding direction. The terminals allow external devices to be connected in series or in parallel. The electromagnet can present the relationship between magnetism and electricity. It induces a magnetic field when electric current is passed through it. • size: 15 x 12 x 3,5 cm
Induction coils QH2410
An aid to explore electromagnetic induction and explain how a transformer works. The primary coils is made of enamelled copper wire of large diameter and very low resistance (ca 0,5 ohm). The secondary coil is wound with fine enamelled wire with resistance 100 ohm. Each coil has two 4 mm sockets. • size: 21 x 15 x 23 cm
