目前磁鐵不能夠(gou)靠近(jin)電(dian)(dian)(dian)器(qi)(qi)的主(zhu)要原因，是(shi)因為一般電(dian)(dian)(dian)器(qi)(qi)內的芯片內含有磁(ci)(ci)(ci)性，所(suo)以如(ru)(ru)果(guo)被磁(ci)(ci)(ci)鐵(tie)碰到了(le)，容易被磁(ci)(ci)(ci)化，芯片、電(dian)(dian)(dian)機(ji)、磁(ci)(ci)(ci)鐵(tie)就(jiu)(jiu)(jiu)(jiu)不能正常工作了(le)，所(suo)以不建(jian)議讓磁(ci)(ci)(ci)鐵(tie)靠近(jin)電(dian)(dian)(dian)器(qi)(qi)，但(dan)(dan)不不是(shi)所(suo)有電(dian)(dian)(dian)器(qi)(qi)都不能靠近(jin)的。如(ru)(ru)彩(cai)色電(dian)(dian)(dian)視(shi)機(ji)圖像(xiang)是(shi)三個陰極發射電(dian)(dian)(dian)器(qi)(qi)磁(ci)(ci)(ci)鐵(tie)的電(dian)(dian)(dian)子束，在(zai)偏轉線圈磁(ci)(ci)(ci)場的作用下，準確地打(da)在(zai)各自的熒光粉上形成(cheng)的。而磁(ci)(ci)(ci)鐵(tie)靠近(jin)顯像(xiang)管會造成(cheng)顯像(xiang)管磁(ci)(ci)(ci)化，如(ru)(ru)果(guo)被磁(ci)(ci)(ci)化，電(dian)(dian)(dian)子分(fen)布就(jiu)(jiu)(jiu)(jiu)不再均勻，也就(jiu)(jiu)(jiu)(jiu)不能正常成(cheng)像(xiang)。短時間使強磁(ci)(ci)(ci)體(ti)靠近(jin)電(dian)(dian)(dian)視(shi)，但(dan)(dan)磁(ci)(ci)(ci)體(ti)長期在(zai)電(dian)(dian)(dian)視(shi)附近(jin)就(jiu)(jiu)(jiu)(jiu)會造成(cheng)電(dian)(dian)(dian)視(shi)損壞，需要消(xiao)磁(ci)(ci)(ci)處(chu)理。但(dan)(dan)是(shi)磁(ci)(ci)(ci)化嚴(yan)重了(le)消(xiao)磁(ci)(ci)(ci)是(shi)消(xiao)不掉的，顯示器(qi)(qi)就(jiu)(jiu)(jiu)(jiu)變色了(le)。
