I was just curious whether there is a difference in horseshoe-shpaed magnets and bar magnets? Which magnet shape is generally stronger, judging from force field and strength? Have there ever been scientific studies about this?
Thanks for helping!

A horseshoe magnet is a bent bar magnet. If two magnets are made from equal amounts of the same material, they would consist of equal numbers (gazillions) of tiny magnets—charged particles—so the overall strengths of the magnetic fields are equal...strengths differ at various points, however.
You can see a picture of the force fields at:

If you want to do a simple experiment to test magnets for field strength, try this website:

You can always use your eyeballs to judge magnetic strength by throwing iron filings (push a magnet through the sand in your backyard to get these free of charge) over the magnets...where the filings line up closest together, the field is the strongest. I would draw a picture, but...

the shape of the magnet relates to the dispersion of the magnetic field not the strength of it.

In the U shaped magnet, the opposite poles are brought close to each other. One pole nullifies the effect of the other. Thus the U shaped magnic fields are weeker.
