Bear in mind that the Aramaean and Assyrian campaigns use different anchors to those used for the Babylonian campaigns. It's interesting (to me) what we can learn from those other anchors.
The destruction of the town of Gath by the Aramaeans (2 Kings 12:18) is one such anchor. Both the archaeomagnetic direction and intensity from Gath show
outstanding agreement with three other destruction layers: Tel Rehov Stratum IV, Horvat Tevet Level V, and Tel Zayit Level XIII. Thus, the archaeomagnetic results strongly support the synchronization of these three destructions with that of Gath, and suggest that they were also the result of the Aramean campaign(s) of Hazael.
Lachish (in the time of Sennacherib) is another anchor. According to biblical and Assyrian sources (2 Kings 18–19; Isaiah 36–37; 2 Chronicles 32), many other Judean sites were
destroyed during that Assyrian campaign but none are securely identified. The archaeomagnetic data from Tel Beersheba, Tel Zayit Level XI, and Tell Beit Mirsim argue for their destruction during the same military campaign.
So, the archaeomagnetic data is excellent for establishing destruction events that happened at the same time as the anchor points, and is moderately good for establishing whether other military campaigns were earlier or later. It in itself tells us nothing about dates.
