Magnetism as an attractive force can overcome gravity and lift things. I'm suggesting that a horseshoe magnet will overcome gravity and lift things off of the ground. Is there a reduction of magnetic pull with altitude?
Typical horseshoe magnet (hard ferromagnetic) attraction to nearby soft ferromagnetic (iron plate) is independent of altitude.I've seen the levitating frog in a magnetic field. I asking if a horeshoe magnet and an iron plate stuck to the magnet. Will altitude decay the force on the plate to where the plate falls off of the magnet
