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.
They make horseshoe magnet babies.
An electromagnet is temporary because the field disappears when the current is switched off.
Magnets don't have to be that shape, but it is sometimes a convenient shape, when using it to attract a piece of magnetic material. Magnets can be straight bars, or cubes, or various other shapes.
Aluminum is not magnet meatal and cannot be a magnet.
by hammering a metal at the magnet xD

The horseshoe magnet is called that because it is shaped like a horseshoe.
A horseshoe magnet has a North pole one one of the feet and a south pole on the other. A magnet made of flexible material would collapse on itself as the two poles attract.
A horseshoe magnet is curved.
The shape - U
They are bar magnet ,horse shoe magnet ,lime stone magnet.
yes it does
There are some variables like what the magnet is made of and how it was initially magnetized. If a bar magnet is bent into a horseshoe shape to make a horseshoe magnet, the magnetic field will be more dense (stronger) across the gap of the horseshoe magnet than it would have been anywhere around the bar magnet from which it was made. And since magnets are strongest at their poles, horseshoe magnets can use both their poles at once while bar magnets can only use one pole at a time.
The direction of the needle will remain unchanged. This is due to magnetic forces, the needle will remain in line with the lines of magnetic force which flow between the north and south poles.
An electromagnet is temporary because the field disappears when the current is switched off.
Horseshoe, Bar, U, Ring, Circle, 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).
