Abstract:
1. A toy including inductively coupleable parts, comprising: a first part including a first inductive element, a first magnet, and a second magnet positioned proximate a first surface of the first device, the first magnet and the second magnet positioned so as to have anti-parallel magnetic dipole moments, the first inductive element having an inductance less than 100 micro-Henrys; and a second part including a second inductive element, a third magnet, and a fourth magnet positioned proximate a surface of the first device, the third magnet and the fourth magnet positioned so as to have anti-parallel magnetic dipole moments, the second inductive element having an inductance less than 100 micro-Henrys; the first inductive element, the first magnet, and the second magnet having a relative spacing to one another that is the same as relative spacing of the second inductive element, the third magnet and the fourth magnet, with spacing between the first inductive element and either of the first magnet or the second magnet being less than 10 mm.
