*Last post of this chapter, & a nice segue to the next…*

- Applications of EM Induction
- Eddy currents
- Generators
- Transformers

*…and now we get to the exciting part!*

- Explanation on EM Induction
- Lenz’s Law

*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

*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

*A tough one (but an interesting one!):*

- Velocity selection
- Hall voltage

**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/m
_{e}for electrons

*Now that we got the basics down, let’s introduce a new term:*

- Magnetic Flux Density
- Tesla
- Measuring magnetic flux density

*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

**We’ve looked at op-amps as comparators & amplifiers, so now let’s look at what their outputs may be connected to!**

- Output devices
- Relays
- LEDs
- Digital meters
- Calibration

*Now, let’s take a closer look at negative feedback.*

- Effects of Negative Feedback
- Inverting amplifiers
- Virtual earth approximation

- Non-inverting amplifiers
- Expressions for voltage gain of inverting & non-inverting amplifiers
