Floating frog in magnetic field
WebScientists have also found many ways to levitate things without any noise or the need for petrol or air, by using electromagnetic fields. Levitating trains and levitating displays are but two examples of electromagnetic levitation. However, a source of energy (an engine or a battery at least) is always required to keep an object afloat. WebMar 17, 2024 · As an upright human is around 30 times as tall as the average experimental frog, the peak magnetic field strength would need to be around $16\sqrt{30}\approx88\text{ T}$, with a corresponding upper bound on the field gradient at equilibrium of $1400/88\approx16\ \mathrm{T/m}$.
