electricity and magnetism

the attractive and repulsive forces between poles

• magnetic forces

• electric forces

• electromagnetic forces

• forces

when an atom losses or gain an electron it will become

• pole

• charge

• ion

• molecule

if an atom looses electron it will become

• negative ion

• positive ion

• molecule

• compound

if an atom gain electron it will become

• positive ion

• polar molecule

• negative ion

• neutral

when ion creates repulsive and attractive forces they create a

• magnetic field

• magnetic force

• electric force

• electric field

when all electron spin in same direction they will create an invisible force know as

• electric force

• electric field

• magnetic field

• magnetic force

magnets have ________poles

• 3

• 2

• 1

• 0

around the poles of a magnet there is area called

• magnetic field

• electric field

• north pole

• south pole

____________is the area around an electric charge where that experience the force exerted by charges

• magnetic force

• magnetic field

• electric force

• electric field

rate of flow of the charged particles is

• current

• circuit

• force

• ion
