Induction Coil, Spark in 15mm Material_LDPE and optic nerve

and optic nerve

running on 3-6V DC to illustrate both motor and generator operation

the wider bore accepting full-size bar magnets while AC current drives the alternating field that rotates domains for demagnetization

sized to retain induced charge through demonstrations of Coulomb's law and surface charge distribution

Induction Coil, Spark in 15mm Material_LDPE and optic nerveThe traditional induction coil capable of producing a spark with an input of 6 to 12 V DC and is therefore ideal for use with vacuum tubes, eudiometers etc. A fully adjustable vibrator system is incorporated and spark suppression capacitors are housed in the base. A pair of pointer electrodes are supplied with the instrument. Pointer electrode have an insulating handle for adjustment of the spark gap. Low voltage input is via a pair of mounted 4 mm
