Neodymium magnet + copper pipe = magnetic damping:
When a magnetic field moves through a conductor a current called an Eddy current is induced in the conductor due to the magnetic field’s movement. The flow of electrons in the conductor creates an opposing magnetic field to the magnet which results in damping of the magnet and causes heating inside of the conductor similar to heat buildup inside of power cords. The loss of energy used to heat up the conductor is equal to the loss of kinetic energy by the magnet.
One note of caution if you decide to try this, these magnets are not for unsupervised children. In fact, everyone should be careful:
Neodymium magnets larger than a half inch are very strong and should be handled with extreme care since they can be dangerous… It is best to stick with neodymium magnets of quarter inch diameter or less.

woah, science. awesome.
If you’ve ever tried to sell anything on Craigslist, you’ve no doubt gotten fraudulent emails from people trying to scam you. These emails are automatically generated by computer programs, contain horrible spelling and grammaer, and promise to wire you money (often more than your asking price)…
this is fantastic. well done @morganhop
In preparation for HOLIDAY SHOWDOWN WEEK next week, i would like to share with you the showdowns from last year’s HOLIDAY SHOWDOWN WEEK.
How about one with Kevin McAlister and The Wet Bandits?
We’re collectively suffering course-envy.Questlove and Spinna were the first to arrive (McBride was stuck in traffic). Questlove immediately launched into how he fell in love with Stevie Wonder’s music. “I spoke with every hip-hop producer I know, that I respect, and we all had the same genesis. It was that one episode of The Cosby Show.” Several in the class nodded in agreement. The episode in question, entitled “A Touch of Wonder,” featured Stevie Wonder recording with the Huxtable family after Denise crashes her car into his limo.
Questlove also described the greatest night of his life. It was an evening where he played with Stevie in Prince’s living room whilst Joni Mitchell “did a drunk girl dance.” It sounded like the greatest night anyone has ever had, ever.
