Hobuseraua ferriidimagnetid, mida nimetatakse ka keraamilisteks hobuserauamagnetiteks või U-kujulised ferriitmagnetid, on õpetamisel ja mängimisel laialt levinud. tuntud ka kui keraamilised õppemagnetid, pakutakse laias valikus suuruste, mõõtmete, kuju ja värviga.
Tavaliselt värvime ferriidist hobuseraua haridusmagnetit mitte ühtegi värvi, punakasrohelist või punakasinist, või ühendame need muu materjaliga, näiteks metalli ja plastiga. Samal ajal vastavad need tooted rahvusvahelistele ohutusstandarditele.
Hariv U-kujuline magnet on laste tervisele ohutu. Valmistame õppemagnetid vastavalt klientide vajadustele. Arvuti, teadus, biotehnika, meditsiiniseadmed ja -riistad, instrumendid ja arvestid.
Tüüpiline magnetiline jõudlus kõva ferriitmagnetiga
