Transcription of FORCES
1 MAGNETIC FORCESYou need to know that: there are FORCES of attraction andrepulsion between magnets AND FORCES of attractionbetween magnets and magnetic QUIZ1. The force that pulls 2 magnets towards each other isa. frictionb. attractionc. repulsion2. The force that pushes 2 magnets apart isa. attractionb. gravityc. repulsion3. Most magnets have 2 ends, these are called the north andsoutha. partsb. polesc. areas4. When the north pole of one magnet is placed next to thenorth pole of another magnet theya. repelb. do nothingc. attract5. When the north pole of one magnet is placed next to thesouth pole of another magnet theya. do nothingb.
2 Repelc. attract6. Which of these is the only magnetic material?a. plasticb. steelc. woodYOUR TASKAim: To test 2 different magnets to find out which has thestrongest magnetic pull or force .(Copy this down)You will need: 2 different magnets, a ruler which showsmm, a paper clip OR pin, a flat table to see how far each magnet can pull your pin orpaper clip along a flat table each magnet in EXACTLY the same way and do thetest 10 times for each magnet . Under the headingMethod, write 4 sentences describing what you did; drawa labelled diagram to help show your results in mm (use a table like the onebelow).Test numberDistance paper clip/pinpulled (mm)Distance paper clip/pinpulled (mm)Bar magnetHorseshoe magnet12345678910 Mean AverageTo work out the mean average just add the 10 resultsthen divide the answer by 10.
3 Do this for both the heading Conclusions write down what youfound out about the strength of your 2 SHEETAim: We wanted to find out which of two_ _ _ _ _ _ _ had the strongest pulling _ _ _ _ : We put a paper clip/pin on the _ _ _ _ _ next tothe 0mm mark on a _ _ _ _ _. We then moved a magnetslowly towards it, along the line of the ruler.
