<upd_detl>No, it's the anode.
It doesn't seem to be used for magnetic poles.</upd_detl>
<upd_refs>GG5: the anode; the negative 「pole [terminal]; a negative electrode.
Eijiro: チウム負極 : lithium anode
For 正極 we see:
GG5: 【電】 a cathode; 【物】 a positive electrode.
中辞典: 〈電池の〉 the cathode.</upd_refs>

<upd_detl>Unfortunately it is not as simple as I had thought: I have a background in electronics, and there the anode (both in a vacuum tube or a semiconductor diode) is positive and the cathode negative (see also https://en.wikipedia.org/wiki/Anode, sections "vacuum tube anode" and "diode anode). So I checked into this matter and found out that in an electrolytic cell (part of a battery), the anode can be either positive or negative depending on whether the cell is charging or discharging. So one could say (as a first approximation) that an anode is the positive terminal in a device to which an external voltage is applied to make same device work, while it is the negative termincal in a device that causes or produces a voltage. Anyway, we always run up against the limitations of a dictionary that cannot be an encyclopedia. :)</upd_detl>

<upd_detl>Yes, the English terminology is confusing and indeed we can't get encyclopedic. I think the glosses for 負極 and 正極 are about as good as we can get. People digging more deeply can see Hendrick's useful comments.</upd_detl>
