Welcome to my little collection of notes & reflections on what I’ve learnt.
Here, I will be making summaries of each topic as I study them, as an exercise for myself.
Here’s a rough outline of how I’ll be explaining each topic:
Deep(ish) Dive: Entropy (Part 1)
While trying to understand certain topics of A-Level Chemistry & Physics, one concept proved to be quite the hurdle: entropy. These posts will detail my current understanding of it – if I do make mistakes do leave a comment! Now, let’s jump straight to the question:
What is Entropy?
Continue reading “Deep(ish) Dive: Entropy (Part 1)”PHY C23: Applications of EM Induction
Last post of this chapter, & a nice segue to the next…
- Applications of EM Induction
- Eddy currents
- Generators
- Transformers
PHY C23: Lenz’s Law & further explanations on EM Induction
…and now we get to the exciting part!
- Explanation on EM Induction
- Lenz’s Law
PHY C23: Electromagnetic Induction
Before this, we have seen how a current-carrying conductor in a constant magnetic field will experience a force. Now we turn to the opposite of this effect:
- EM Induction
- Magnetic Flux Linkage
- Factors affecting the magnitude of induced e.m.f.
- Faraday’s Law
PHY C23: Magnetic Flux
New chapter! Let’s start off with a very important concept:
- Magnetic Flux
- Φ = BA sin θ
PHY C22: NMRI
After exploring Ultrasound, let’s dive into another form of medical imaging!
- Principles behind the use of NMRI
- Functions of
- uniform magnetic field
- RF pulses
- non-uniform magnetic field
PHY C22: Charged Particles in Electric & Magnetic Fields
A tough one (but an interesting one!):
- Velocity selection
- Hall voltage
PHY C22: Charged Particles in Magnetic Fields
So far we’ve explored forces on permanent magnets & current-carrying conductors. But what about free-moving charged particles?
- Force on a charge moving in a magnetic field
- F = Bqv sin θ
- Determination of v & e/me for electrons
PHY C22: Magnetic Flux Density
Now that we got the basics down, let’s introduce a new term:
- Magnetic Flux Density
- Tesla
- Measuring magnetic flux density
PHY C22: Magnetic Fields
A new field!
- Magnetic Fields
- Magnetic Field Lines
- Force on a current-carrying conductor in a magnetic field
- F = BIL sin θ
- Force between parallel current-carrying conductors
