Unfortunately electric current can only be generated using change in magnetic field. So this won't work with a static magnetic field, as is the case in the article.
- tantalor 13y agoStatic is relative. Spin a wire loop around a static magnetic field and you get a current, right?
- tanvach 13y agoOnly if the loop moves, which actually experiences changes in magnetic field
- zer0gravity 13y agoThe article says: "They placed a coil at one of the tube that generated a magnetic field of 1.3 mTelsa" So didn't they generate the magnetic field by running a current through that coil, in which case we're talking about a changing magnetic field?
- leephillips 13y ago"So didn't they generate the magnetic field by running a current through that coil" Yes. "in which case we're talking about a changing magnetic field?" No. Why?
- zer0gravity 13y agoWas under the impression that if a changing magnetic field induces a current in a wire then running current through a wire will produce a changing magnetic field around it, but apparently is not the case, it produces a static magnetic field.
