- static
- not moving, but eventurally does move.
- magnetic field
- the invisible force that loops between the poles of a magnet due to the arrangement of charges.
- poles
- the strongest part of the magnets
- insulators
- are material that do not become charge easily. plastic, rubber, wood, glass.
- static electricity
- The imbalance of positive or negative charges between 2 objects.
- electric current
- The flow of an electric charge through a material.
- series circuit
- electric charge can flow only in one path, one direction around asingle loop and recived the same amount of electricity.
- 2 objects with the same charge
- push away, or repel each other.
- circuit
- loop
- opposite charge
- positive and negative pull toward each other.
- brakes in paralle circuit
- does not stop the charge from flowing.
- positive electric field attracts
- negative charges and pushes away positive charges.
- electricity and magnetism
- is the result of charged paticles moving.
- static electricity stays
- in one place.
- how do magnets work?
- each magnet has an invisible field arount it.
- An electric current
- travels quickly and invisible.
- magnet
- anything that attaracts other things made of iron,steel, certain materials.
- Antartica
- located in the magnetic south pole.
- the flow of electric charge is not the
- same in all materials.
- aurora
- caused by charged particle sfrom the sun being attract to Earth poles.
- electromagnet
- is the coil of wire with many loops through which an electric current passes.
- atoms
- tiny building blocks of everything.
- electric force
- pull or push between objects that have a different charge.
- charge object
- attract something that have no charge.
- why earth is like a magnet?
- Earth outer core is made of iron as Earth rotates electric currents flow to create a magnetic field.
- different amount of electrical current
- parallel circuit
- why compass needle alwasys move to north south?
- because Earth behaves like a large magnet.
- attract each other
- north pole one one magnet and the south pole on another magnet.
- parallel circuit
- 2 or more paths for the electric charge to flow.how the charge flow through each little loop does not affect the flow of charges.
- electric current
- is electric charge in motion
- magnetic poles
- north seeking and south seeking
- Canada
- the magnetic north pole
- if you break a magnet into 2
- 2magnets
- electric field
- space around electrically charged objects. It invisible. Its strongest close to the charge object.
- same amount of electrical current
- simple circiut
- resistance
- a quality of an object which means that electric current cannot flow easily through it.
- particles have 3 types of charges:
- positive, negative and neutral
- conductors
- copper wire , silver are excelent conductors of electric charge.
- how you can make the electromagnet strongest?
- 1. increasing the amount of current running through the wire.2.increase the number of coil,3magnetic core larger.
- what have a huge magnetic field?
- the Earth.
- Magnetism
- force that acts on moving electric charge and magnetic material that are near a magnet.
- scientist invent the circuits to study
- how electricity moves.
- closed circuit
- has no breaks and allows an elctric current to move through it.
