In general, yes. Horseshoe magnets are usually more sturdy while u-magnets are basically toys. I'm open to correction here.
Horseshoe, Bar, U, Ring, Circle, etc.
only one... but there are difrent shapes...
They make horseshoe magnet babies.
yes
I can tell you more.Bar,disc,horseshoe,u-shaped etc.
Magnet shaped like a horseshoe, so both the polarities are pointed the same way. They can be weak or strong magnets (my dad had a couple when we were kids... we put a broomstick in them and did chin-ups from the I-beam in the basement, because they were strong enough to hold a 12-year-old's weight easily). Here is a site with a picture of some: http://www.indigo.com/magnets/gphmgnts/chrome-steel-horseshoe-magnets.html
When the north and south magnets face the opposite pole.
In general, magnets are brittle and will break before they bend. And yes, refrigerator magnets bend, but in them the magnetic material is powdered. But if we took a bar magnet and bent it, we'd have a horseshoe magnet. It's not quite that simple to make a horseshoe magnet, but it isn't too tough, either.
Horseshoe magnets have a stronger magnetic field at their poles compared to bar magnets, which have a more uniform magnetic field along their length. The horseshoe shape concentrates the magnetic field lines at the poles, making them more effective for picking up magnetic materials. Bar magnets have a weaker magnetic field at their ends but are more versatile in their application.
Horseshoe magnets are used to teach the properties of magnets to students. They are also used to pick up metal items.
they either stick together or push away
Hardware stores such as Lowe's, Ace, and Home Depot may have a drawer in the fasteners section that is labeled "Science Experiments" and may carry small horseshoe magnets of a size commonly used in science classes. There are many vendors online that will sell magnets, one of which is www.unitednuclear.com, where they sell a wide variety of magnets designed for more complex experiments. Also, in many Canadian cities Dollar shops have those magnets.
