[QUOTE="hutchphd, post: 6830926, member: 635497"] Also the geometry of the magnet is very important. Much more holding strength can be obtained for a lifting a solid object if the object completes "magnetic circuit": this is why a horseshoe magnet can hold much more than double the strength each of its pole faces individually. Also one must be aware that an electromagnet core reaches saturation beyond which more current (or windings) does little to help your cause. This is why strong magnets (or power transformers) need to be big chunks of iron. There used to be nice software [/QUOTE]
