When two neutral objects are rubbed against each other, one object may pull electrons away from the other creating one positive object and one negative object.
Conduction
An object can be charged by touching it with another object that already has a charge. The resulting object will then have the same charge but weaker in strength than the original object.
Induction
Objects do not touch (one is charged, one is neutral)
Proximity of the charged object causes (induces) the charges in the neutral object to separate.
