You can use WolframAlpha to check calculations like that.

I thought the method was wrong because it gives us d=1mm but we don't use it in our calculations.

I'm not sure where the Hall voltage is measured, either 0.330mm or 1mm is not necessary.

Take a look at the Hyperphysics web page on the Hall Effect.

@Turion: Your calculation looks good.
