This discussion centers on the feasibility of holding electrified liquids, particularly water, in the air using external electric and magnetic fields. Participants reference the "Milliken Oil Drop Experiment" and discuss the principles of magnetic levitation, noting that while frogs have been levitated due to their high water content, practical experiments with water have not been widely conducted. It is established that achieving this levitation requires extremely high magnetic fields, approximately 10-15 teslas or more, to counteract gravitational forces.
PREREQUISITESPhysicists, engineers, and researchers interested in magnetic levitation, experimental physics, and the behavior of liquids in strong magnetic fields.
I was thinking something like molted iron or metal, that's also my question, I'm not sure what it could be. I want to know whether the liquid could be held up only by the magnetic field or electric field.Bystander said:What is an electrified liquid?
Thank you Bystander. These seem very interesting. I checked quickly the levitating frog, I read "...Frogs are convenient (for the experiments) not only because they have a high water content, which is a good diamagnetic material...", so it seems convinced that if one applies a strong enough magnetic field to some volume of water, the water could be held in the air, is it right? But no one has done this kind of experiments? I am picturing in mind some volume of water held in the air by the magnetic field, and then (by turning off the magnetic field) falls down.Bystander said:You might want to hunt down the "Milliken Oil Drop Experiment." Magnetic levitation using attractive and repulsive effects has been applied in a variety of apparatus, "spinning rotor gauges" for vacuum systems. For liquids? Frogs levitating in high magnetic fields are a popular gimmick in laboratory public relations, and are arguably liquid.
