magnetic portion 16 at the end of the wand 10 while the three portions 12 14 16 of the wand 10 are explicitly illustrated in fig1 the extended portion 14 and the magnetic portion 16 may appear to be a single integral portion without the line 18 the magnetic portion 16 may be as large e g 50 of the length of the wand or small only at the end of the wand 10 as the user would like in fig1 the wand 10 has an oval cross section but it could have any appropriate cross section including for example round square or simply elongated with a number of discrete sides e g hexagonal pentagonal etc the building blocks 20 illustrated in cross section in fig2 2 a and 2 b could be of any style size shape configuration or from any maker e g legos mega bloks etc with a ferromagnetic material 22 that is attracted to the wand 10 the ferromagnetic material 22 may be of any appropriate materials for the purpose of inclusion in the building blocks 20 the ferromagnetic material 22 may be molded in the building blocks in a number of ways the ferromagnetic material may be included as a single piece as ferromagnetic material 22 u2032 as in fig2 a or multiple pieces as ferromagnetic material 22 u2033 as in fig2 b the ferromagnetic material 22 is depicted as a powder or smaller particles particulates in fig2 the ferromagnetic materials 22 22 u2032 and 22 u2033 should be sufficiently encapsulated in the building blocks 20 so as prevent.
