The Poem!

Have you heard of magnets 
and all that they can do?   
They push, they pull, they pick things up 
And stick to fridges too! 
 
Which objects can they move? 
A sausage? Or a lion? 
No, they only work on metals  
Like nickel and like iron 
 
And aluminum and gold? 
Can magnets move them too?  

No, they don’t like every metal 
They only like a few 
 
But how does this all work? 
How can they do so much? 
With a force called magnetism 
That we can’t see or touch 
 
What else can you tell me 
That's interesting and true? 
Planet Earth has North and South Poles 
And magnets have them too! 
 
Every time that North’s near South 
They pull each other near 
If North meets North?  Or South meets South? 
They shout “GET OUT OF HERE!” 
 
One last thing, please tell me 
How strong these magnets are

Well, some just pick up paper clips 
But some can hold a car!
