I have now bought a copy on eBay, scanned it to a PDF file and uploaded it to the documents section of my Vintage Radio Info website - it's the last link in the first section. It's quite large 9. The book was first published in and is no longer available. It shows its age in the style of the illustrations - all painted no photographs with good clear detail.

By Steve Bush 7th March On the radio yesterday morning were some interviews with folk that were in at the start of Ladybird Books. I had forgotten all about that title, but a copy of that Ladybird Book was one of the childhood inspirations that got me into electronics. I also remember that the page on series connection had a string of three bulbs connected in series, and that the one nearest the positive battery terminal was the brightest, and the one nearest the negative terminal was dimmest, as I recall — so either the artist was given an odd set of bulbs, or someone thought that electricity ran out as it went around the circuit….? The image is taken from Amazon, where you can buy the book.

Water is dimagnetic, which means that it exerts a weak magnetic field, and repels other magnetic fields. If a magnet is suspended over water, the water's dimagnetism will repel the magnet. This weakens the magnet's effect on other objects. When salt is added to water, it weakens the water's magnetic field further, so that it ceases to have any significant effect on other magnetic fields. However, salt water conducts electricity better than non-salt water, so magnets placed near it can cause significant turbulence in the water. Dimagnetism refers to an object's tendency to generate a weak magnetic field in opposition to a magnetic field applied to it.

There's absolutely no doubt that I was something of a geeky child. I had a chemistry set and also a selection of batteries, bulbs and electric wires. I also had a magnet set that I loved so much that when I saw the same one for sale on eBay last year in new condition I bought it instantly to put away for Little Miss C and her, then still a bump, baby brother. It's no wonder that I went on to study physics and chemistry at A-Level and engineering at university. I would have loved the Ladybird Junior Science Book Magnets, Bulbs and Batteries — in fact some of the projects look so familiar that I am actually wondering if I did own a copy when I was younger, or if not it must have been a very similar book. The Junior Science series series contained just 4 titles Magnets, Bulbs and Batteries, Light, Mirrors and Lenses, Air, Wind and Flight and Levers, Pulleys and Engines but all were written to guide children from the fundamental scientific principles through to experiments to encourage independent thinking and understanding.
