詳細內容：繞在U型鐵棒上的銅線圈即產生了密集的磁場，這樣就使U型鐵棒變成了一塊“電磁鐵”。這種電磁鐵上的磁能要比永磁能大放多倍，它能吸起比它重20倍的鐵塊，而當電源切斷后，U型鐵棒就什么鐵塊也吸不住，重新成為一根普通的鐵棒。 聯系人：蔡韻 手機：一八七七一零二二八二九 手機：18771022829 qq3121226951/1287946729 02-414112 KBFDG4V333C20N10ZM2PE7H711 02-414115 KBFDG4V333C07NZM1PH7H711 02-414141 KBFDG5V733C160NXM1PH7H110 02-414167 KBFDG5V72C200NEXM1PH7H110 02-414168 KBFDG5V733C160NEXM1PH7H110 02-414187 KBFDG5V833C375NMRE5400L-D1N1N1S1NX0201/33800 MRE5400L-D1N1N1S1NX0300/58123 MRE5400L-F1N1N1N1NX0300/58083- MRE5400L-F1N1N1S3NX0300/54789- MRE5400L-F1N1N1S3NX0300/59345- MRE5400L-F1T1N1N1NX0300/58612 MRE5400L-F2N1N1N1NX0300/34959 MRE5400L-F2N1N1N1NX0300/58198 MRE800F-D1N1N1N1N0900/59840 MRE800F-F1N1N1S1NX0900/59574 MRE800F-F1N1N1S1NX0902/60837 MRE800F-P1N1N1N1N0900/59607 MRE8200M-D1N1N1S1NX0500/59088 MRE8200M-F1M1N1N1NX0000/33374 MRE8200M-F1M1N1N1NX0400/58078 MRE8200M-F1M1N2N1NX0500/59075 MRE8200M-F2N1N1N1N0500/59123 MRE8200M-F2N1N1N1NX0400/58207 MRE8200M-F2N1N1N1NX0400/58225 MRE8200M-F2N1N1N1NX0500/59214- MRE8200M-N1B1N1N1N0500/60049 MRTE10800P-D1N1N1G1N0300/60853 MRV1800H600F2N1N2N1NX0900/6065 MRV2800I1263N1Q2N1N1SX0601/607XM1PC7H110 02-414204 KBFDG4V333C07NZM2PE7H711 02-414205 KBFDG4V59C50NZM2PE7H711 02-414236 KBFDG4V52C50N25ZM1PH7H711 02-414245 KBFDG4V333C20NZM1PC7H711 02-414253 KBFDG4V533C50N25ZM2PH7H711 02-414364 KBFDG4V533C70NZM1PE7H711EN56 02-414369 KBFDG4V533C30NZM1PH7H711 02-414371 KBFDG4V333C20NZM2PE7H711 02-414437 KBFDG5V533C60N40EXM2PE7H110 02-414440 KBFDG5V82C375N250EXM2PE7H110 02-414449 KBFDG4V52C70NZM2PH7H711 02-414492 KBFDG5V52C95NEXM1PH7H110 02-414621 KBFDG5V52C95NXM1PH7H110 02-414628 KBFDG5V733C160NXTM1PE7H110 02-414632 KBFDG5V52C70N45XM2PH7H110 5992991-001 KBFDG5V1033C700NEXM1PC7H110 5993030-001 KBFDG4V52C75N45ZM2PE7H711
