Quite the opposite.It is strongest at the poles.Try this:-
Take a bar magnet,lay it flat on the table, take a piece of iron and touch it on one of the poles...it will pick the magnet up.If you touch it in the middle ,between the poles it will not pick the magnet up,there is hardly any magnetic field in the middle.

It depends on the shape of the magnet of course. Generally, the strongest fields you will measure are right outside the poles where the field lines emerge all bunched up. This is easy to see if you draw a picture of the field lines bending from one pole to the other.
For a toroid (donut) or helix (slinky) magnet, the lines do converge in the middle, so that's the strongest B-field.

For a bar magnet, the lines of magnetic flux are closest together in the middle - so yes.

Yes if it's shaped like a donut.
take a piece of paper , put it on top of your magnet and sprinkle iron filings on top of the paper and you will see it's strength by the amount of filings attracted to particular areas.

no its strongest at the points
