2017年2月13日 · Normal neodymium magnets will lose their magnetic properties if heated above 175°F (80° C). The strong magnetic fields of neodymium magnets can damage items such as televisions, computer monitors, credit cards, bank cards, computers, diskettes and other data carriers, video tapes, mechanical watches, hearing aids, loud speakers and VCRs.

2020年4月6日 · Most of the character in that type of construction derives from the steel poles. Changing the magnets won't make much of a difference. Especially in this case, because the permeability of ceramic magnets and neo magnets are both extremely low (translation - the magnets don't influence the inductance very much at all).

2011年3月22日 · I use the epoxy coated 1" x 1/4" neodymium magnets for the Outside magnets on my frag racks. I don't think I would trust them for very long on the inside. I did buy a couple 1" x 1" 1/4" square rubber coated neodymium magnets and they do seem like they have much more coating on them, than the epoxy coated ones.

2016年9月2日 · I'm just not sure what the long term effects are in a reef system. The standard two part epoxy is initially reef safe but who knows if it eventually breaks down. acrylic is 100% so long as the seams are welded properly. that's the major issue with the magnets that come with commercial frag racks like eshopps. a lot of people, myself included, have had leaks with their …

2020年3月28日 · Rare earth or neodymium magnets will kill every coral and invert in your tank pretty quickly. Even if these are epoxy coated, if the coating cracks that tiny hole can sometimes leach fast enough to kill coral. The only safe magnets are …

2023年1月23日 · Neodymium magnets can not be used (unless plastic coated. These are best magnets you can buy that are reef safe, you can find them at K&J magnetics). Even the epoxy coated ones will eventually leach. Ceramic magnets are safe but not 100%, basically use at your own risk but proven to work. The downfall with Ceramic is they are not very strong.

2019年6月22日 · Super Strong Neodymium Disc Magnets with Epoxy Coating, Powerful Permanent Rare Earth Magnets 1.26 inch x 1/8 inch, Pack of 10 Amazon product I like the idea. I’d probably go with something like this.

2022年3月10日 · Neodymium magnets have never offered me equal or better tonality than Alnico or Ceramic. I do understand their popularity because of their weight compared to the other two magnet types but, when I start looking at the best for specific musical styles, they just never get …

2014年2月3日 · easy peasy. lotsa good ways to charge pickups. all you need to fill up the magnetism tanks on yer pickup's alnico rod mags is a pair of 1/2" to 1" diameter neodymium rare earth disc magnets. it doesn't hafta be a bar mag and the mag doesn't need to come into direct contact with the alnico rod mags (in fact, i don't want that to occur). i got my neo mags online …

2015年10月12日 · I used 1" x 3/8" neodymium magnets for the inside. I found some re-useable molds just a little bigger than the magnets. I used polyester casting resin with black dye ( to block uv rays) to coat the magnets and to attach the black eggcrate.
