Objective Diagram a magnetic field These two magnets

Objective: Diagram a magnetic field These two magnets will… a) Repel each other b) Attract each other c) Refract each other d) Not interact with each other q. Magnets q. Magnetic fields

This is magnet.

A Magnet is… metal that attracts iron.

Interesting facts about magnets: 1)All magnets have 2 poles S is for South Pole N is for North Pole

Interesting facts about magnets: 2) Break a magnet, each part will still have 2 poles.

Interesting facts about magnets: . 3) Like poles (South and North) repel each other (push each other away)

Interesting facts about magnets: 4) Unlike Poles (South and North) attract each other (pull each other together)

These two magnets will…. a) b) c) d) S N Attract and pull each other together Repel and pull each other together Attract and push each other away Repel and push each other away

These two magnets pull towards each other. These two magnets push away from one another. Why?

These are all the things you can see.

This is what you can’t see. Magnetic Fields
