Hi everybody! Speaking about industrial electromagnets, like this one:

=BFIs an electromagnet like this, strong for attract nearby
ferromagnetic objects? =BFHow closer they need to be to get attracted
strongly? or =BFare they strong just for holding ferromagnetic objects?
(particulary, at the webpage where shows this electromagnet, they say
that it can hold 500 lb just using a 1,5 v "D" size cell, so it=B4s
obvious that this class of electromagnets are too good for holding
ferromagnetic objects; what i need to know is how good are the to
attract and how strong they attract nearby objects)
