It is called a Basket.

South Pole
When an iron piece is quite away from the magnet ,i.e, not present in magnetic field of the magnet then the iron piece is in neutral state ,i.e, there is no north & south pole . But , as soon as the iron piece interacts with magnetic field of magnet ,i.e, near to the magnet then the north pole of magnet make the nearer part or end of the iron piece south pole & simultaneously other part of iron becomes north pole . Similarly if south pole of the magnet interacts with iron piece then that end/part becomes north pole & other end becomes north pole . Now this iron piece has north & south pole .So iron piece is now converted into magnet which can attract other iron pieces in similar way as explained before .
No
what is the pole of the umbrella called
the inner side is south pole and outer side is north pole.
Dowel. It does not have to be long either. It could be as short as a 1 inch and still be called a dowel.
Doubt it because the piece of steel is not magnetized.
It is called the pole vault pit.
Perhaps because it needs only a central support pole?? Circus tents are not always round although a round design is the best for general vision. Small circuses toured with a central pole in the middle of the ring and this was called 'a one pole tent'. A central section could be added called 'the centre' placed between two poles and this would be called 'the two pole tent' with still a central ring clear of the pole but the audience would be quite near at one side and further away at each end - not as good really to the one pole tent. The much more recent four pole tent is more ideal and can be of varying sizes to suit the required seating capacity or size of the circus. A small four pole tent, say, 80ft in diameter, could seat about 1000 persons whilst the largest (in my experience being Billy Smart) could seat up to 6000 persons. The central ring is an agreed size of 42ft in diameter.
A post, stake, pole.
