Hey...
I think its some confusion here :P
3 ways of making magnets
By induction ( complicated process will be studied later ). Pieces of iron( permanent) or steel ( temporary )
And thn later... :
IRON AND STEEL
Iron is a soft magnetic material ( easy to charge and easy to lose charge )--> temporary magnets
Steel is hard magnetic mat. ( hard to chagge and heard to lose ) --->permanent
Am i gettin sumthin wrong...or its supposed to be that way ? ???
And thx alot for ur notes...M gonna read them out soon :)

Ok you know whats the middle finger tells you current. ( CONVENTIONAL CURRENT ) and we all know that electrons ( beta ) go the opposite way of the conventional current right?
So alpha partcles are +ve and they go opposite way of beta
in other words : CONVENTIONAL CURRENT + AND ALPHA are found by the normal LEFT HANND FLEMIMNGS RULE
If u wanna find beta.. u find the direction of the conventional current..the direction of movement of beta will be opposite of the conventional current
this is for magnetic field By the way
CHECK MAY JUNE 2003 LAST QUESTION FOR PRACTISE!
SoONa:
hey r we suppose 2 know the quantity of charge for static electricity ive seeen it in notes somwhere but i really dont understand it .. and its not in ur notes ???
