1. new class: magnetism. in this class we will find all of releted to magnets like:

1. electrons. sigh: [ELCT]. there traval in stright lines and you can set what is the
direction of the track and the velocity by click-draging. when there strike metal, there spark that.
2. plastic. sigh: [PLST]. this not conducts electricity but can charging and move charged particles.
melt at 450C and broke at -75C.
3. charges. sigh: [-CHRG],[+CHRG]. charged targted element(if possibe to chrage). broken metal and broken plastic, for example.
5. magnetic fields. sigh: [OMGF],[IMGF]. one rotate electrons CW and other CCW. the rotate is dependent on velocity.

and more backgrond: electromagnetic fields (photons maybe will be charged, too.)

at electricity class will be magnet switch(or electromagnet) sigh: [EMGT]. one mode it make magnetic
field and one mode it make elegtric field.

if there will more ideas, i will update.

bye.
