所有所涉及的电子感觉消极HSC物理学模块6：电磁？
Don’t fret, we’re here to walk you through it!
Last year, we talked about Electric Fields in ‘Module 4: Electromagnetism.’ We covered:
- Charged Objects & Interactions
- Electric Circuits, and
- 磁性物体
Now that we have built the foundations last year, it is time to “build the house” on top of these foundations as we look at how electric fields and magnetic fields interact with one another for some useful applications in our everyday lives.
在本文中，我们将为您提供HSC物理模块6的概述：电磁和分解每个询问问题，并为您提供Acing本模块的前3个提示！
So, what are you waiting for? Let’s jump right in!

从旧模块的变化
In the changes from the old syllabus (which was Topic 2: Motors and Generators), a stronger focus on concepts is prevalent rather than a mix of concepts and their impacts in society and on the environment.
我们还通过效果背后的定量数学进行了更深入的研究电磁诱导。
What’s There to Learn in HSC Physics Module 6?
In HSC Physics Module 6: Electromagnetism, we’re taking a deep dive into the world of electromagnetism, including;
- 电场make a return, with this time a focus onhow particles are affected by them
- You’re back usingElectric Circuits, except this time you are focusing on在与磁场接触时如何移动电线
- 你一起合并了两个想法how electric fields and magnetic fields relate to one another
- 你看技术进步和日常机器如何使用效果和法律在这个主题里面。
- There are a lot ofequations在这个主题中，有很多数学来包裹你的头。
HSC物理模块6的概述：电磁
现在我们将浏览每个询问问题并分解其关键概念！
Inquiry Question 1: What happens to stationary and moving charged particles when they interact with an electric or magnetic field?
这部分的主题都是关于particles travel through both an electric and magnetic field.
When talking about charged particles and an electric field, you imagine a tiny “charged particle cannon” firing these particles through these fields to produce parabolic paths, just as if you fired a cannonball.
要知道您的粒子是否为正或负面，这也很重要，因为这可能对电子的路径和力产生剧烈影响。
关于磁场，重要的是从南方告诉你的北方以及充电的粒子在进入磁场时如何发生反应。
进入垂直时，粒子会从该字段中获取最大“OMOMF”，而如果您正在平行于该字段，则无效。
查询问题2：在磁场中携带电流携带导体上产生的力在什么情况下？
你看电机效果，电流承载导体和均匀磁场之间的效果。
请记住，当我们的磁场垂直于电流承载导体时，实现最大力，并且如果该字段平行地，则在导体上没有产生任何力。
接下来，在本节中，您认为两根线并排行驶（并联）彼此相互行进。
虽然对立面的反对与积极和负面收费一起吸引，但如果此信息“窗外”朝向电流方向时，则会夹住所有。
您注意到，相反的电流方向排斥并在彼此行驶的那些彼此绘制时彼此产生推力。
Inquiry Question 3: How are electric and magnetic fields related?
您会陷入磁通量如何变化，即面积中磁场量的测量。
You also observe how an electric force can be generated by a moving magnet according to Faraday’s Law and how that current created travels in the opposite direction to the one that created it, by Lenz’s Law.
You also delve into transformers and how solenoids use the effects of Faraday’s Law and Lenz’s Law.
Whilst you do discuss imperfections such as the resistive heat production of transformers, you ignore these in our calculations as the ratio of voltage to the number of coils remains constant across transformer coils.
Inquiry Question 4: How has knowledge about the Motor Effect been applied to technological advances?
当我们看看如何在简单的DC电机内涉及，您继续建立在电机效果上。
You’ll put on your builder’s hat as you put together a DC Motor with parts like the Axle and Rotor and how torque, the force of rotation, is produced by these motors.
在操作电机时，EMF也根据Lenz和Faraday的定律在反向方向上生成，您在左手规则中使用以确定其后退EMF。
Finally, you incorporate the overarching Law of Conservation of Energy and how this law helps getting a DC Motor turning and how we stop trains and rides with magnetic braking.
3 Tips to Getting a Band 6 in HSC Physics Module 6
Tip #1: Right Hand Rules are Your Friend
Throughout this topic, there is going to be a lot of scenarios where you’re using the Right Hand Rule.
Whether it’s a current-carrying conductor moving through a magnetic field or a spinning motor, it’s important to know your right hand rule to indicate which direction your motor will spin or which way your wire with move.
不要害怕在考试中使用这些，因为它们非常有用地指示正确的方向，并且可以获得一些容易的多种选择标记。
提示＃2：了解您的涡流
Eddy currents are prevalent throughout many aspects of this topic, particularly how they resist total energy transformation within transformers.
We need to know how these eddy currents “spin” in the opposite direction to the currents that created them (as according to Lenz’s Law) and how the heat created is an unwanted energy transformation as opposed to the transformation of the voltage.
Tip #3: Learn Lenz and the Reverse
Lenz’s law also appears in many different circumstances of this module.
我们用它来描述电线和螺线管中的电流方向。
虽然我们可以使用左手规则来描述这一点，但更容易将此描述为“与右手规则相反”以释放一些内存进行考试。
We also note that Lenz’s law plays a vital role in creating back emf in the opposite direction and important in magnetic braking technology to slow down fast moving trains.
And that wraps up our guide to HSC Physics Module 6: Electromagnetism – good luck!
