A flux loop is a loop of wire placed inside a plasma at a right angle. Changes in the field create a current in the loop, which may be interpreted to measure the properties of the plasma. Flux loops are key diagnostics in fusion power research. == Theory == A flux loop is a loop of wire. The magnetic field passes through the wire loop. As the field varied inside the loop, it generated a voltage, driving a current. This was measured and from the signal the magnetic flux was measured. The voltage induced is determined by:〔"Principals of Plasma Diagnostics" Second edition, I H Hutchinson, page 11, 2002〕 : Typically, you need to integrate the signal over a period of time to get the magnetic field at that instant (not just the change in magnetic fields). This is normally done by adding a integrator circuit which will passively integrate the electrical signal. : 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Flux loop」の詳細全文を読む スポンサード リンク
