How is Static Electricity Produced? Static electricity is produced when one object takes negative charges from another object. For example, amber becomes negatively charged when rubbed with wool, because amber attracts negative charges (electrons) and will take them from wool. As a result, the amber becomes "negatively charged," and the wool, due to its loss of negative charges, becomes "positively charged". The distribution of electrical charges in amber and wool before and after rubbing is shown below:
