The tesla coil, invented by Nikola Tesla, creates big sparks and can wirelessly power a fluorescent lamp. It consists of two coils and capacitors to store energy for discharge. Building and observing tesla coils is a popular activity among science enthusiasts. The largest tesla coil in the world produces 1.5 megavolts of current and 20-foot […]
The tesla, named after Nikola Tesla, measures magnetic field strength. One tesla is 30,000 times stronger than Earth’s magnetic field. The most powerful superconducting electromagnets produce fields of about 20T. The most powerful continuous magnetic field measures 45T, while the most powerful destructive pulse magnet measures about 850T. Medical MRI typically claims a field strength […]
Nikola Tesla, the father of modern electricity and inventor of the radio, made significant contributions to science and engineering, including the invention of alternating current, the AC motor, and wireless transmission of power and signals. However, his legacy has been tarnished by exaggerated claims about his technology, including the harnessed cosmic rays for energy and […]
