## Questions & Answers

**Q: Do i need to buy both a north and a south pack in order to make my door stick? or does a pack include plain steel rings for the magnet to stick to?**
A: No, no plain steel rings are provided. But be careful when choosing screws to attach the magnets. Use brass or any non magnetic material. I initially made the mistake of choosing a metal screw, and it opposed the magnetic force.

**Q: Would this be ok to use as a replacement magnet on a treadmill?**
A: It might work, but why take the risk when you can get a purpose-designed replacement for less than £2 on eBay.

**Q: what is the radius**
A: The diameter of this magnet is 20mm and then the thickness is 3mm.

**Q: What do i need to hold up lightweight curtains, say five north p magnets inside the curtain hem and five south p magnets screwed into the window?**
A: They would support curtains but depends on curtain length as to how many
