In part 2 of my MRI series, I discuss how an external magnetic field affects the magnetic moment of the hydrogen nucleus. In particular, how it aligns and precession. Both are explained at length in a non technical fashion
Want to know how the eye focuses or accommodates? This video goes through the physics of accommodation, how the eye adjusts in order to produce a sharp image on the retina. It also covers long and short sightedness and how to fix them.
This video covers how crystals are used to create and receive high frequency sound. Apart from their use in small speakers, they are especially useful in their used of transducers for ultrasound imaging.
A follow up of my first video on circuits, this video explores the mathematics. of circuits, with the use of Ohm’s Law to determine resistance, voltage and current, in both series and parallel circuits.
