It’s really easy to experiment with at home. It is driven by the Lorentz force - the force which is exerted by a magnetic field on a moving electric charge. When a battery is placed on top of a magnet, and a wire then connects the top of the battery back down to the magnet, the circuit is complete.
Students in our Summer Schools were making these the other day. This one won the ‘most creative design’ competition <3
Our “tough” boy, hurt himself.. In the house! He hurt his right front leg, and there is no feeling or movement past his “knee”. His vet bills are going to be pricey, and he deserves the best treatment available. Can you help with his bills? He deserves to be able to run, jump, and play again!!!
Hey guys! I know I don’t often ask for help, but please help spread this for my dad. Zoom is such a lovable little guy full of life and energy. My dad recently took in two strays and money has been tight, and now Zoom can’t even play like he used to. My dad recently lost another cat, as well, and I know it’d break his heart if he had to lose another so soon because he couldn’t afford care. Please, every little bit helps. I absolutely love and adore this cat.
