💁🏻♀️ ICYMI: ⚡🧲 #Cambridge #math professor Hannah Fry demonstrates how to build a simple electric #motor using a #battery, #copper wire, #magnets, and paper clips.
Winding wire into a coil creates an electromagnet that repels and attracts the magnet beneath, forcing the coil to spin.

PhET Interactive Simulations has just released a new course, Teaching #Electricity and #Magnetism with PhET Simulations.
You will explore PhET’s electricity & magnetism simulations, learn from model lessons, and design your own custom sim-based lesson plans. bit.ly/ElectricityMagnetism #teacherPD -
By the way. My 24kJ capacitor bank discharges enough energy to cause a small EMP, which in turn scrambles digital clocks within 20 feet or so. Isn't that nuts?

CRUSHED! Induction launcher + HDD platter + pop can + pancake coil
#highvoltage #electricity #induction #Coilguns #magnetism #launcher

OK folks of Mastodonland, I finally dug out my "small" induction launcher that I built well over 20 years ago.
It consists of 16 capacitors, 3600uf @ 350vdc each. 8 each are wired in parallel to form two banks, which are then wired in series, giving 700v. Then two of those in series for 1400v (~3.5kJ). An SCR triggers discharge into a pancake coil, and a large diode prevents back-emf from killing the SCR.
In this demo, you see what happens with just 44vdc...now imagine a full 1400vdc... And then imagine my larger 24kJ bank.....

Experiments prove the existence of "a new type of magnetism" called altermagnetism. Well that's interesting... although I read the article and as best I can tell there's no practical implications or applications at the moment..
