Magnetism - Hold Tight

 I love the way the little trains and carriages of the Brio hold on to each other, like magic. Setting it up, I’ve explained to my grandchildren that opposites attract and pull to stick together. Do it the other way round and they push away. Fascinating to me, but not to those who know how it works and just want to get on with playing. Magnetism.

“We know, Nanna.”

And of course, they do. Or at least, they did before lockdown separated us for what feels like eternity. I hope they can come back soon.
 

We’ve done the bit about magnets having north and south and it only works on metal. We’ve checked different things in my house as we’ve wandered around with Brio trains. The fridge is good, and the freezer. We already know that because my collection of picture magnets are holding the children’s art-work in place. Central heating radiators are good, but not the metal legs on the small table.

“Why?”

 “They are made of a different metal that is not magnetic. You’ll learn all about it when you’re older and have science lessons at school.”

One started school in September and is bursting to get back.  He loves it and misses it. One will start this year, if life gets back to normal and two of them will return to nursery. Luckily for them, I’m fine with science up to Key Stage One.

When I was a child, I had one of those magnet-based toys which consisted of a face and bald head beneath a thin, clear screen. At the bottom were lots of iron filings which could be carried clump by clump on a magnetic pen up to the screen, and placed to make hair, eyebrows, moustache and beard. I played with it for hours.

Science was not a core subject when I was at school. I chose the option of History in preference.  These days I would choose both.  I’ve found some interesting stuff on BBC Bitesize, electromagnetism and magnetism on KS3 Physics. We’re never too old to learn.

I found this children’s song on a primary education website. Author not credited.

It’s a magnetic world.
The Earth’s a magnetic place.
Everywhere, all around, you’ll find magnets.
In computers and t.v sets
and microphones,
They even hold doors closed around your home.

Every magnet has a north pole,
A south pole too.
Each pole has its own molecules.
They create a force,
A magnetic field,
That attracts metals like iron and steel.

Magnets, many sizes and shapes
Horseshoes, bars and cylinders
Magnetic discs large and small
Magnets working for us all.

It’s a magnetic world.
The Earth’s a magnetic place.
Put two magnets together, what can you tell?
North and south poles will attract
And like poles together will repel.

Every magnetic field if it’s strong enough
Can pass through paper, wood or plastic.

You can make a magnet with electricity
And it’s very strong, you will see.

Magnets, many sizes and shapes
Horseshoes, bars and cylinders
Magnetic discs large and small
Magnets working for us all.

It’s a magnetic world.
The Earth’s a magnetic place.
Everywhere, all around, you’ll find magnets.
