Yes, permanent bar magnets can lose their magnetism if heated above their Curie temperature, subjected to strong opposing magnetic fields, or physically damaged.
A bar magnet is straight, with poles at opposite ends. A horseshoe magnet is bent into a U-shape, bringing the poles closer together to create a stronger, more concentrated magnetic field between them.
It is an open compound noun, written as two separate words: 'bar magnet'. It is not hyphenated in standard modern usage except occasionally when used attributively (e.g., 'bar-magnet strength').
