Hello!
There is an interesting effect that I've discovered in magnets while studying E&M and experimenting.
If the surface area where the magnet will be attracted to,for example the surface area of the steel plate is x4 times larger than the magnet, then there would be a stronger attraction force, it would take a lot of effort to pull the magnet off. However, this does not happen to a small steel nail x4 times smaller than the magnet.
Nothing but the "area" has changed in both cases however, the magnet is the same in both.
What is the proper explanation of this?
I contacted the manufacture of my magnets, they said it's true because of the area being x4 times larger and thicker than the magnet itself that would cause the whole magnetic field of the magnet to be "held". Is this right? What do you all think of this?
I think they have it posted on their website, I'll try to get the link soon.
