The 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.
