When two magnets are close, they create pushing or pulling forces on one another. These forces are strongest at the ends of the magnets. A magnet has two en ds: the north pole an d the so uth pole. N S Some magnets are stronger than others. Strong magnets will create bigger pushing or pulling forces than weak magnets. © Teacher’s Pet 2013 www.tpet.co.uk What happens if we put 2 magnets together?

Magnetic forces are often very strong compared to other forces, so they can be used to lock doors and gates and even hold carriages together. The ‘Stealth’ roller coaster ride at Thorpe Park accelerates to 80mph in un der 2.3 secon ds. They use magnets to help the ride slow down and brake safely. © Teacher’s Pet 2013 www.tpet.co.uk
