Everything else in the magnetism range carries an under-8 ingestion warning; a 50mm painted block does not, because it will not go anywhere. That makes it the one a prep teacher can actually put on a table.\u003c\/p\u003e\u003cp\u003eThe printed N and S are doing real teaching work. A child holding two blocks discovers that red-to-blue pulls and red-to-red pushes, and the letters give them the vocabulary at the same moment they feel the force. No worksheet required.\u003c\/p\u003e\u003cp\u003eFerrite has high coercive strength, which in practice means it stays magnetised through years of being dropped, banged together and left in a tub with everything else.\u003c\/p\u003e","brand":"MTA Essentials","offers":[{"title":"Default Title","offer_id":53792723960171,"sku":"EVDC51008","price":2.8,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/2795\/8891\/files\/dc51008_large-ferrite-block-magnet_v4_2.webp?v=1788350571","url":"https:\/\/megaofficesupplies.com.au\/products\/large-ferrite-block-magnet-50mm","provider":"Mega Office Supplies","version":"1.0","type":"link"}
