ELECTRICITY AND MAGNETISM
STATIC ELECTRICITY

Static electricity is
when a charge builds
up on a material.
 EX:
Has your hair ever
stood on end while
combing it? Well that is
static electricity at work.
INSULATORS
A material that
resists the flow of
electricity or heat.
 EX- dry wood
rubber
plastic
glass

CONDUCTORS


Material that can carry
electricity or heat.
EX- metal
silver
gold
aluminum
water
copper
humans
CIRCUITS
The pathway that
electric current
follows is called an
electric circuit .
 To make an electric
circuit you need:
wire
battery
light bulb

SIMPLE CIRCUIT

Using two or three
wires, one battery,
and one light bulb.
PARRALLEL CIRCUIT

A closed electrical
circuit in which the
current is divided
into two or more
paths and then
returns by a
common path to
complete the
circuit.
SERIES CIRCUIT

An electric circuit
connected so that
current passes
through each
circuit element in
turn without
branching.
BAR MAGNET
Attracts- iron, steel,
nickel, cobalt
 Has North and South
poles
 Unlike poles attract
 Like poles repel
 Strongest at poles
 Made of magnetite

ELECTROMAGNET
Attracts iron, steel,
nickel, cobalt
 Has no poles
 Has different
strengths
 Temporary
 Made of wire, battery,
iron

HOW THEY ARE THEY ALIKE



They attract the same
objects.
They are surrounded by
magnetic fields.
They are both metal based.
HOW THEY ARE DIFFERENT




An electromagnet can be
controlled.
A bar magnet has north and
south poles.
A bar magnet is permanent.
An electromagnet is
temporary.
