Magnetic field value assigned to a magnet meaning

[anorred]

When a magnet has a value of.. let's say 10 Tesla, what does this mean exactly? Does this mean the magnetic field value directly on the poles has a value of 10 Tesla?

A proper magnet description should specify where the field is measured. 10 Tesla looks like the (maximal?) field value somewhere - it is an electromagnet, so it does not have poles.

What do you mean it doesn't have poles?

Tesla is a unit of magnetic flux density (B) i.e the number of 'lines per square metre' and so the position should be given.
10T is a very strong (large magnetic flux density) field strength

Try to define poles as points in space for an electromagnet without a core, and you will see the problem.

Data sheets often specify the maximum induction present within the magnetic material itself. If that is the case for your magnet, then values at the poles will generally be lower.

The question incolves a magnet (which I take to be permanent), and does not specify an electromagnet.

There are no permanent magnets with magnetic fields of 10 Tesla.
If you check my two previous posts, I made clear that, and why, they refer to electromagnets.
