Not necessarily.
The small bar magnet has a stronger magnetic field, at least at short distances.
A bar magnet is a magnet of rectangular shape with a north and and south end, which are sometimes coloured different colours to indicate which end is which.
They are bar magnet ,horse shoe magnet ,lime stone magnet.
A horseshoe magnet is curved.
Not necessarily.
No, electromagnets are stronger than bar magnets.
The small bar magnet has a stronger magnetic field, at least at short distances.
Horseshoe, Bar, U, Ring, Circle, etc.
Please note that a magnetic field is not measured in units of acceleration (or the equivalent force / mass), like gravity is. What exactly happens when a bar magnet falls through a metal ring will depend on the details of the situation - for example, how strong the magnetic field is, and the mass of the bar magnet.
No. The magnet has a sort of symmetry, in the sense that its two sides are "equal but opposite".
A bar magnet is a magnet of rectangular shape with a north and and south end, which are sometimes coloured different colours to indicate which end is which.
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.

There is no restriction in the shpae of magnet it can be of any shape but the most common shapes are horseshoe, bar and ring
no
Move towards the U magnet so that the poles attach.
