Morning time

My sleep pattern has normalized lately since I fell ill almost two weeks ago. Haven't heard a word from Drona or Diya. The treacherous D's!
I woke up early today to finish a physics homework I was supposed to have finished over the weekend, which I spent studying and understanding integration. The homework is about "How to detect magnetic fields" using a search coil, a hall probe and a current balance. Now while the two former devices are understandable and simplistic, the latter is complex and intricate.
I was looking up videos and websites on the net all morning trying to figure out how to explain the working principle of a current balance and found nada...nichts...nothing! Well nothing that made sense to me! And then I realize that there is a simplified model of the current balance in the book! Fricken Page 376! It's so annoying to put all that back breaking work into an assignment! And finally be thwarted/rescued by a simple diagram in ur textbook! Why didn't I look there before.
Should be testament to the fact that I've never truly studied the text book before. Better start now! I have less than an hour before class starts!
Wish me luck!
