2SGen v1.0 is an amazing Solid State Generator very simple to build, you will observe some very interesting results about the properties of a toroidal coil with a ferromagnetic core when it is used with a neodymium magnet
/ 2SGen V1.0 是一个了不起的固态发电机,非常容易制作,你将观察到配合钕磁铁的铁氧体环形线圈的许多有趣的结果
The toroidal coil uses a ferromagnetic core (grade 3E25) specific inductance Al=3820 (23x14x7 mm) (µ=6000), Rdc:1.4 ohms,
and it is wound CW with 7.5 m of 4/10 mm copper wire,
The magnet is a 10 mm diameter and 5 mm thick neodymium magnet,
The output coil is a air core flat coil (OD: 42, ID:18mm, TH: 8mm) inductance=636 mH, Rdc=990 ohms made with 450m of 0.1 mm diam copper wire
