ⓘ Os textos do jogo estão em inglês.
Só ferro e aço são atraídos; cobre e alumínio não. Polos iguais se repelem e diferentes se atraem.

Como jogar
- Pick up: drag the magnet onto things; iron things are pulled in and move with it. Choose paper, glass or wood below to try through them, flip the magnet or put things back.
- Poles: dip it in clips and count, then tick Break in two. Two magnets: flip and push to see attract or repel. Compass: drag, flip and turn the magnet and watch the needle, with optional small compasses.
- Levels: what magnets attract, the two poles, like poles repel, the compass, and attracting through things.
Unidade do currículo
Primary science, grade 2: what magnets attract, attracting through things, the two poles, how poles push and pull, and making a compass (Jiaoke science, grade 2 volume 2, unit 1).
Para pais e professores
Only a classroom bar magnet is simulated. Mistakes are grouped as "all metals are attracted", missing iron things, where and how many poles, like and unlike poles, compasses near magnets, attracting through things and distance. Remind children to keep magnets away from phones, cards and watches.
Perguntas frequentes
Do magnets attract all metals?
No. Magnets attract iron and steel (and things with nickel or cobalt). A brass key, aluminium foil and drink cans are not attracted.
Where is a magnet strongest?
At its ends, the poles; the middle hardly attracts. A bar magnet has an N (north-seeking) and an S (south-seeking) pole, and each broken piece still has both.
Why does a compass point north?
The needle is a tiny magnet and the Earth acts like a giant magnet, so the N end points north. A magnet nearby pulls or pushes the needle, so the reading is wrong.
