Description
6Aとなる交流電流を各コイル10a,10b,20a,20bに流す。なお、この場合において、磁界強度が不足する場合、制御部50は、バイポーラ電源30を制御して電流値を高め、例えば24Aとなる交流電流を各コイル10a,10b,20a,20bに流す。これにより、低周波数域において強い磁界強度を生成する。
24Aとなる交流電流を各コイル10a,10b,20a,20bに流す。これにより、高周波磁界を実現する。
10…内側コイル(1対のコイル)
20…外側コイル(1対のコイル)
10a,20a…第1コイル
10b,20b…第2コイル
30…電源
40…信号発生部
50…制御部
60…切替部(切替手段)
a,b…コイル
L…接続線
SW1〜SW5…スイッチ
Claims (1)
