World's Strongest Magnet! - Summary

Summary

The world's strongest magnet, located at the National High Magnetic Field Laboratory in Tallahassee, Florida, has held the Guinness World Record for the strongest continuous magnetic field since 2000. The magnet has a field strength of 45 Tesla, nearly a million times stronger than Earth's magnetic field. It consists of an outer superconducting magnet and an inner resistive magnet, and is two stories tall. The magnet can levitate non-magnetic objects, wreak havoc on camera equipment, and even affect the behavior of non-ferromagnetic materials.

The magnet is used for material science and condensed matter research, and can induce Eddy currents in conductive materials, causing them to heat up or slow down. The magnet's fringe field, which extends above and around the magnet, can also affect objects.

The video also explores the concept of superconductors and how they can be used to levitate objects. A superconductor is a material that has zero electrical resistance, and can expel magnetic fields. The video shows how a superconductor can be used to levitate a magnet, and even a human.

The strongest magnet was created by combining an outer superconducting electromagnet with an inner electromagnet made of ordinary wire. The superconducting outsert produces 11.5 Tesla, while the resistive magnet produces 33.5 Tesla, for a total of 45 Tesla.

The magnet is extremely expensive to operate, consuming about 8% of Tallahassee's total generating capacity and costing around $250,000 to $300,000 per month. However, it is a valuable tool for material science research and has the potential to lead to new discoveries and breakthroughs.

The video also touches on the concept of paramagnetism and diamagnetism, and how some materials are always attracted to or repelled by magnetic fields. This can be used to levitate objects, even living organisms, in a strong enough magnetic field.

Overall, the world's strongest magnet is a powerful tool for scientific research, and has the potential to lead to new discoveries and breakthroughs in materials science and beyond.
