The discussion centers on the interaction between magnetism and gravity, specifically how a horseshoe magnet can lift objects against gravitational pull. It is established that the force between two magnets decreases with distance according to the formula 1/r^4. However, the magnetic attraction of a typical horseshoe magnet to a soft ferromagnetic material, such as an iron plate, remains unaffected by altitude. Magnetic levitation technology, effective up to 30cm, is also referenced, highlighting its practical applications.
PREREQUISITESPhysics enthusiasts, engineers, and anyone interested in the principles of magnetism and its applications in technology such as magnetic levitation.
Typical horseshoe magnet (hard ferromagnetic) attraction to nearby soft ferromagnetic (iron plate) is independent of altitude.homerwho said: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
