The force of this magnet is ___ of all. A. the strongest B. stronger C. strong D. the stronger 相关知识点: 试题来源: 解析 A。“of all”表示在所有当中,要用最高级,“strong”的最高级是“the strongest”,B 选项“stronger”是比较级,C 选项“strong”是原级,均不符合。
The MagSafe magnet is N52H which is one of the strongest magnets on the market. Instructions: Please inspect the Grippy for damage before use. Make sure the surface you are attaching to is flat, smooth, and clean. Before letting go of the phone, please make sure the Grippy has obtained ...

The strongest permanent magnets have fields near 2 T; superconducting electromagnets may attain 10 T or more. The Earth’s magnetic field on its surface is only about 5 × 10−5 T, or 0.5 G. The direction of the magnetic force F is perpendicular to the plane form...
The bismuth disks arediamagnetic. This means that they push away from a magnet. It doesn't matter whether the north pole of the magnet or the south pole is used, the bismuth always pushes away. The diamagnetism is very weak, even in bismuth, which has the strongest diamagnetism of any me...
Bar magnet, flat poles (interesting “dog-bone” shape to the field strength diagram!) Bar magnet, rounded poles (field is strongest at the center of the rounded pole!) Two magnets attracting (strong field in the middle between the magnets!) ...
In the vast majority of applications, the small angle of magnetization direction error doesn't matter. Sticking a magnet to a fridge? It still sticks strongest on the pole faces. Small changes in magnetization angle don't seem to affect pull force in our tests. ...
However, it might surprise you that direction finding is nearly as old as radio itself. In 1888, Heinrich Hertz noted that signals were strongest when in one orientation of a loop antenna and weakest 90 degrees rotated. By 1900, experimenters noted dipoles exhibit similar behavior and it wasn...
the intermetallic compound Nd2Fe14B, discovered in 1984, remains the strongest commercial magnet and is used in many of the aforementioned applications4,5. This dearth of progress in discovering new magnets stems in part from the empirical approach historically used to synthesize inorganic materials,...
Further, a magnet is disposed around the processing chamber to generate a magnetic field perpendicular to the upper surface of the wafer and a microwave transmitting window is disposed in the ceiling of the processing chamber. Also, a microwave generated by a microwave generator is introduced into...
