## Description

desertcart.com: CMS Magnetics® Ceramic Magnet 1 7/8" x 7/8" x 3/8" Rectangular Magnets, Package of 12 Ceramic 8 Hard Ferrite Magnets : Industrial & Scientific

Review: Great Magnets - Incredibly Strong! - I needed something strong enough to hold mosquito netting to the inside of my car door, and had previously purchased some magnets from WalMart that were woefully inadequate. I was unsure when ordering these, but they arrived promptly and are incredibly strong -- so strong that it's almost hard for me to separate them. They seem very sturdy and will work perfectly for what I need them for, but when handling them they do "slough off" or leave some sort of dark residue on my fingers (but it is easily brushed off.) Also, I do think that if dropped, they might shatter... the good thing is that they're strong enough, I don't have to worry about them coming loose and falling on their own... I just need to be sure not to drop them :)
Review: Strong magnets I use on my fridge to hold things there. - Really like my set of magnets that came neatly packed in a little box. These are robust magnets. Yes they have dust on them but you can just wipe them off with a wet cloth before using them and then it is okay. I just use mine to hold up bunches of paper stuff on my fridge and they are strong and do an excellent job for that. It can easily hold a good 10 sheets or more of paper 8 x 11 on a fridge very securely. I don't know if they break when dropped because I have never dropped them for how I use them. Mine have always lasted for years and still really stick to the fridge, real good!

## Questions & Answers

**Q: Do these have mixed pole in each side or North on one and South on the other?**
A: N and S poles are on the opposite flat surfaces.

**Q: I was wondering what the strength of this is?**
A: I absolutely love these magnets.  I have no way to measure the strength I just know that they are very strong magnets and I like having several to use in many ways.

**Q: I need magnets to hold down curtains on a windy day on the screened-in patio. Will these work for that?**
A: They are heavy so they will hold a curtain down for soft breeze.  If stuck to steel they will hold quite a bit more but a curtain is a lot of sail area so the more wind the more of the magnets you will need.  How many depends on the size of the curtain and the strength of the wind.

**Q: can these magnets be cut?**
A: Yes they can. Almost anything can be cut. They may not do the job you want but have at it. Caution as they are quite hard and brittle.

### ⭐⭐⭐⭐ Useful for exploring magnetic concepts.

I bought these to use as part of several class activities. They worked well but a few students were overly rough and several broke leaving sharp points.
