Show There are No Isolated PolesEvery magnet has two poles, North and South. But when you break a bar magnet in half, it doesn’t divide into a “North” piece and a “South” piece. Instead, each broken piece has its own North and South pole. Now your students can verify this intriguing fact for themselves. Set of 2 bars are notched so it's easy to break them into four 1.7cm-long miniature magnets. Size: each bar is 7cm long With a 8mm x 4mm cross section.
