Over the period which Dr Penn and Dr Livingston analysed, the average magnetic strength of the irruptions has declined.

佩恩和利文斯顿博士分析表明，入侵活动平均磁场强度已有所下降。

While the U.S. has more tornadoes than any other country, tornadoes only form once out of every 10 strong storms.

虽然美国龙卷风比其他任何国家都，但10场强风暴只有1场能形成龙卷风。

The problem is that the theory puts white dwarfs' magnetic fields at 100,000 tesla or more, well beyond humanity's reach.

问题是，这个第一原则认为白矮星磁场强度可以达到100,000特斯拉或，远远超过了人类极限。

Some neutron stars generate fields 100 billion times stronger than those found in sunspots.

一些子星产生场比太阳黑子场强 1000 亿倍。

Like Susan's an artist. Lynette's a great businesswoman.

就像苏珊是艺术家 勒奈特是职场强人。

B is the strength of the magnetic field at each point along the loop.

B是磁场强度 循环个点。

Scanning at the resolution required to determine the details of individual synapses would requires a field strength high enough to cook a person's tissues.

以确定单个突触细节所需分辨率进行扫描将需要足够高场强以制造人组织。

But a couple of other things induced emf, too, even if the strength of the magnetic field stayed the same.

但是，即使磁场强度保持不变，其他一些因素也会引起电动势。

But when that core collapses, the strength of the field skyrockets, and a neutron star can easily have a magnetic field several trillion times stronger than the Sun's.

但当其核心坍缩时，它们磁场强度会急剧上升，一颗子星磁场很轻易就会比太阳强几万亿倍。

And if the magnetic field and the loop are perpendicular, then the magnetic flux will just be equal to the strength of the magnetic field times the area of the loop.

如果磁场和环路垂直，那么磁通量将等于磁场强度乘以环路面积。

And there are three factors that affect the magnetic field, and therefore the magnetic flux through the loop: First, there’s the strength of the magnetic field, which we label as B.

影响磁场并因此影响通过环路磁通量因素有三个：首先，是磁场强度， 我们将其标记为 B。

So! The change in magnetic flux is equal to the strength of the magnetic field, times the length of the loop, times the change in its width within the magnetic field.

所以！ 磁通量变化等于磁场强度乘以环长度，乘以其在磁场内宽度变化。

So when Dr Murdin placed the crystal in a 30-tesla magnet at Radboud University in the Netherlands (his lab in Guildford lacks the necessary kit), he was mimicking the conditions in a 100,000-tesla white dwarf.

因此，当穆迪博士这个晶体放到一个30特斯拉磁体（这个磁体在荷兰内梅根大学）时，因为他在格尔福德实验室缺少必要设备，他是在模仿一个100,000特斯拉磁场强度白矮星所处环境。

This planet's magnetic field is 10,000 times stronger than Earth's, so it traps huge amounts of particles and supercharges them, meaning that the radiation levels around Jupiter are about what you'd get near a nuclear explosion.

这颗行星磁场强度是地球 1 万倍，所以它捕获了大量粒子并对它们增压，这意味着木星周围辐射水平与核爆炸附近水平相当。

In 1960, the General Conference on Weights and Measures honored Tesla's memory by deciding to use his last name – Tesla – as a unit of measure for the strength of a magnetic field.

1960 年，国际计量大会为了纪念特斯拉， 决定使用他姓氏——特斯拉——作为磁场强度度量单位。

Combining all these factors, we find that the magnetic flux is equal to the strength of the magnetic field times the area of the loop, times the cosine of the angle between the magnetic field and that perpendicular line.

结合所有这些因素，我们发现磁通量等于磁场强度乘以环路面积，乘以磁场与垂直线之间夹角余弦。
