things you will need
- 4 x magnets
- 2 x pieces of card (two colours)
- Pen or pencil
- 1 x grown-up (see safety notice)
- Keep magnets out of reach of small children who may put them in their mouth.
- Magnets can also interfere with electronic devices, so keep them away from phones and other screens.
Make the hearts
- Take the two pieces of card and fold them in half – one on top of the other.
- Draw half a heart shape, with the straight edge being the fold.
- Cut along the outline to reveal your two heart shapes.
Prepare the sliders
- Cut four same-sized strips using the remaining card.
- Lay the magnets out, on the end of each strip of card.
- IMPORTANT: Make sure that for each pair of red and blue strips, the magnetic poles facing upwards are opposite. For instance, Blue – North, Red – South.
Stick down the magnets
- Using the magnet as a guide for size, fold the strips over 4 times.
- Place the magnet in the centre section of each strip and tape down.
- Fold each strip into a box and tape together.
Time to set-up
- Pair the red and blue boxes that attract each other.
- Tape them to the heart shapes.
- Turn your magnetic hearts over and SNAP them together.
- When it comes to magnets – opposites really do attract!
How it works
- Magnets produce an invisible force called magnetism.
- This force will pull some metals towards the magnet (metals that contain iron, nickel and cobalt).
- All magnets have two polar (opposite) ends – these are called the north and south poles.
- Two poles of the same type (e.g. North and North (will always repel each other. This is described as magnetic repulsion.
- Two poles that are different (e.g. North and South) will attract each other. This is called magnetic attraction.
- Magnetic attraction is used in this project to snap the two half hearts into one.
