Also, hard on the heels of. Directly behind, immediately following, as in Mom's birthday comes on the heels of Mother's Day, or Hard on the heels of the flood there was a tornado. The hard in the variant acts as an intensifier, giving it the sense of "close on the heels of". [Early 1800s] Also see at one's heels.

Definition of magnet in English:

1.1A person or thing that has a powerful attraction:the beautiful stretch of white sand is a magnet forsun-worshippers
1.2archaic term for lodestone.

WIKIPEDIA
先驅者十號和十一號上的氦矢量磁強計

磁強計(英語:magnetometer)又稱作磁力儀高斯計,指的是各種用於測量磁場的儀器,。

國際單位制中描述磁場的物理量是磁感應強度,單位是特斯拉。由於1特斯拉意味著非常強的磁場,地球科學上常用納特來作為測量單位,工程上常用的CGS制(厘米-克-秒制)中,單位則是高斯。在早期,電磁領域高斯單位盛行,因此磁強計也稱為高斯計。

磁感應強度是矢量,具有大小和方向特徵,只測量磁感應強度大小的磁強計稱為純量磁強計,而能夠測量特定方向磁場大小的磁強計稱為矢量磁強計。

能夠測量磁場的物理原理有很多,根據不同原理進行分類,常見純量磁強計原理有質子旋進磁強計,Overhauser磁強計,鹼金屬光泵磁強計等,常見的矢量磁強計有磁通門磁


Magnetometers can be used as metal detectors: they can detect only magnetic (ferrous) metals, but can detect such metals at a much greater distance than conventional metal detectors which rely on conductivity; they are capable of detecting large objects, such as cars, at tens of metres, while a metal detector's range is rarely more than 2 metres.

In recent years, magnetometers have been miniaturized to the extent that they can be incorporated in integrated circuits at very low cost and are finding increasing use as miniaturized compasses (MEMS magnetic field sensor).


gear
(ENGINE PART)
noun [C or U]
a device, often consisting of connecting sets of wheels with teeth around the edge, that controls how much power from an engine goes to the moving parts of a machine:
Does your car have four or five gears?
I couldn't find reverse gear.
The car should be in gear (= with its gears in position, allowing the vehicle to move).
When you start a car you need to be in first/US ALSO low gear.
FIGURATIVE After a slow start, the leadership campaign suddenly shifted into top gear (= started to advance very quickly).



be in [out of] gear ギヤがきく[きかない]; 調子がよい[悪い].
get into gear 順調に動き出す.
in high [low] gear 高速[低速]で[の]; 調子が最高[最低]で[の].

In October, as the holiday gift season was getting into gear, The Wall Street Journal purchased four recalled Mattel Inc. toys from sellers on Taobao.com, China's leading online consumer auction site. The toys included a Barbie kitchen set with lead paint, a Polly Pocket play set containing potentially deadly magnets and a Fisher-Price infant swing that was recalled world-wide because 60 infants suffered cuts, bruises and other injuries after getting trapped between the swing seat and its frame. On any given day that month, the site had listings for dozens of other recalled Mattel goods, with some sellers suggesting they had as many as 100 of each toy for sale.
《華 爾街日報》記者在去年10月聖誕購物季開始升溫時在中國領先的購物網站──淘寶網(Taobao.com)上買到四套美泰公司(Mattel Inc.)已宣佈召回的玩具。其中包括因涂料含鉛而被召回的芭比娃娃廚房套件(Barbie kitchen)、因帶有可能致命的磁石零件而被召回的芭莉口袋娃娃(Polly Pocket)套件﹐以及Fisher-Price的嬰兒鞦千。此前曾有60名嬰兒因為被卡在這種鞦千的座椅和構件之間而被割傷、擦傷或是受到其他傷害﹐ 因此該產品在全球範圍被召回。而在整個10月份﹐淘寶網上隨時都可以找到十幾種已宣佈召回的美泰產品﹐網站上的一些商家甚至暗示每一種商品的待售數量都達 到上百件。
