Hello! How can I help you today?
assistant
I'm curious about magnets. What is magnetic levitation?
user
Magnetic levitation, also known as maglev, is a technology that uses magnetic forces to lift and suspend objects in mid-air, without any physical contact.
assistant
That sounds cool. How does it work?
user
It works by using electromagnets to create an upward magnetic force that counteracts the weight of the object, allowing it to float above a surface.
assistant
I see. Is magnetic levitation used in real-world applications?
user
Yes, magnetic levitation is used in some high-speed trains, such as the Shanghai Maglev Train, and also in some industrial and scientific applications, like magnetic bearings and particle accelerators.
