What that means in practice
Neodymium is the strongest family of permanent magnets in common use, and N52 is a high grade within it. At 20mm each sphere is large for a magnet ball, so the pull between the two is firm.
A sphere has no fixed face. Each ball can turn freely and settle into line with its partner, which suits demonstrations and hands-on experiments. Nothing else is needed to use them: no power supply, no mounting kit.
Handling
Keep them well away from pacemakers, bank cards, phones and small children. Let the two balls come together slowly. Neodymium is brittle, and a hard collision can chip it or pinch skin in between.
