# Solar Magnetic Field

Solar dynamo + flux transport

## Importance

- solar activities
- space weathers

## Known facts

- magnetic field from under the sun

## Studies

- hard to observe magnetic field
- Use acoustic wave
- sound -> temp

# Solar meridional flow

- Axisymmetric flow along meridional plane
- 10 ~ 20 m/s
- Solar cycle
- Extends to the entire convective zone.

## Result

- magnetic field from below the sun
- 16^o^ = max'

## Measurements

- $\delta r$
- compare $\delta r$ and flow speed

# Magnetic field at surface

## Stoke's parament

- EM wave propagating
- linear retarder

# Sunspot

- black

# Special Topics Space for Sophomore students

無人...機?

# 心得
儘管之前因為已經底修所以沒有上到老師的服務學習課程，儘管自己本身對於科學的探討沒有那麼有興趣，但是工程來自於科學的需求，因此多了解這些科學的研究方法與需求，能讓我更加知道以後要做甚麼。
