Electricity& Magnetism It’s electric and charged !

Attraction  When two objects with opposite charges pull on each

Bar magnets  Magnets in the form of a bar with magnetic poles at each end

Charge  A measure of the extra positive or negative particles that an object has.

Conductor  Material that allows current to easily flow.

Electric circuit  a path along which electrons flow

Electric current  A flow of electric charges

Electric field  The space where electric forces occur around an object

Electromagnet  A temporary magnet made by coiling wire around an iron core; when current flows in the coil the iron becomes a magnet.  A temporary magnet made by coiling wire around an iron core; when current flows in the coil the iron becomes a magnet.

Insulator  Material through which a current cannot pass or easily flow Examples of good insulators are plastic, wood, glass, and rubber.

Series circuit  An electric circuit that has only one path for the current.

Parallel circuit  An electric circuit that has more than one path for the current.

Static Electricity  A charge that stays on an object instead of flowing in a current.

Repulsion  the force with which particles or like forces repel one another
