Lets get a little technical when we discuss how electric motors work. In every switch and twitch, physics is at work. We wont bore you with terms you cannot comprehend because we created this book to be age-appropriate for fourth graders. Trace actions and see pictures for easier comprehension. Would you like to create your own electric motors too?
