Mickey's Magnet (1956) Originally included a real magnet (lightly glued to the inside of the back cover), this book tells the story of how Mickey learns about magnets -- what they pick up, what they don't, and why. The final page encourages the reader to use the enclosed magnet to experiment: "Here is a magnet you can use," it offers. "Mickey picked up pins with a horseshoe magnet," it continues. "Can you pick up pins with your bar magnet? ... What else can you find out about your new magnet?"
