Hi all. Unsure if asked before here. Trying again.
A magnet fitted with long, straight, parallel pole pieces; will it yield a constant magnetic field strength between them, near or distant from the magnet ?
======================================================================== <--- long iron bar polepiece
N
magnet
S
======================================================================== <--- long iron bar polepiece
A piece of iron across the polepieces, placed near the magnet; at the middle of length or placed at the far right a few metres away will attach with the same force ? In other words, will the magnetism be attenuated by lenght of polepieces ?
