This year is a real brake. It's magnetic. It is activated by a magnet.

今年开放线路有刹闸，是磁感应，磁驱动。

For a hatchling sea turtle, the answer is magnetoreception.

对于刚出壳海龟来说，答案是磁感应。

The predictions agree with experiments up to the strongest fields mankind can muster—about 1,000 tesla, generated in a thermonuclear detonator.

结果，预测与试验完全一致—即达到人类在这个领域最高水准，能够在热核雷管中产生1000特斯拉磁感应。

Ten years later, he discovered electromagnetic induction, a fundamental principle regarding how generators, which change mechanical energy into electrical energy, operate.

十年后，他发现了电磁感应，这是关于发电机如何将机械能转化电能基本原理。

This is an electric induction oventhat uses electricity and induction power of magnets.

这是一款电感应烤箱，利用电力和磁感应原理进行工作。

And so that is electromagnetic induction.

那就是电磁感应。

So to understand that you really have to understand the specifics of electromagnetic induction.

所以要理解这一点，你需要了解电磁感应具体细节。

It's called a magnetic induction brake system, powered by a deceivingly simple physics concept known as an eddy current.

这被称磁感应制动系统，由一个看似简单物理概念——涡电流驱动。

It is on electromagnetic induction which is the ability of a magnetic field to create current inside a conductor.

这是关于电磁感应，即磁场在导体内部产生电流能力。

And so we are going to have induction and we are going to have current.

所以我们将会产生电磁感应，并且会有电流。

Intagliata: Which is one more piece of evidence that the cryptochrome protein might underpin the robins' magnetic sense.

这又是一个证据，表明隐花色素蛋白可能是知更鸟磁感应基础。

That molecule gets activated, energized, and one of the effects of that is to turn on the magnetic sensory system.

该分子被激活、通电，其效果之一是打开磁感应系统。

And so was there electromagnetic induction?

那么，有电磁感应吗？

And so if we ever have change in that magnetic flux, then we are going to have electromagnetic induction occurring.

所以如果磁通量发生变化，就会发生电磁感应。

No, the idea that thought and emotion at one location can impact thought and location, another one is that Magneto reception has been published in the journal science.

不，这种观点认， 某一地点思想和情感能够影响另一地点思想和位置，另一个观点是， 磁感应现象已在科学期刊上发表。 因此，我们并未超越现实界限。

The abbey had installed a wire - called a hearing loop or induction loop - which transmits sound via a magnetic signal to the telecoil in a hearing aid or cochlear implant.

修道院是安装了一种助听线圈（也叫电磁感应线圈），这种线圈能够通过磁信号将声音传播给助听器或人工耳蜗。

And so the electricity that you are using right now and the microphone that I am using right now as well, use this idea of electromagnetic induction.

你现在在使用电和我在使用麦克风，都利用了电磁感应原理。

Peter Hore is a physical chemist on that team at the University of Oxford in the U.K. Hore: We know the magnetic sensors are in the bird's eyes, in their retinas.

彼得·霍尔是英国牛津大学团队中物理化学家。霍尔：我们知道磁感应器位于鸟眼睛中，具体在视网膜里。
