Review: Very powerful. Be careful. - These things are so strong even with the little plastic between them. It is very difficult to get them apart. I once got two of them too close together and it was difficult to get them apart without the spacer so be careful.
Review: They are just powerful enough but yet again maybe not. - I made a jig using the head of a carriage bolt on a GoPro camera with this magnet on the other side of it as a tripod mount. Just strong enough but not enough. I'll buy more but they'll be a lot more powerful than these are.

## Features

- 【PROFESSIONAL USE】Replacement equipment automatic transmission fluid pan magnets have wide application in industry area. For this small ring magnets, they can be applied in projects, product manufacturing, scientific experiment, brushless motor, solenoid and vehicle filter.
- 【DAILY USE】There are a hundred uses for these handy little magnets in your daily life. You can use them to store the special wrenches for large tools right on the surface of the tool or use double-stick tape or some super glue to adhere them to non-metallic surfaces. Used for bulletin boards, DIY arts-crafts and hobby.
- 【SCIENCE TRIAL】The strength of these magnets will be seen in science experiment. Young students age 6-10 will be more interested in this magical power. Prepare a pencil, a block of wood, some magnets, show magnet levitation. Built a simple electric motors using safety pins, copper wire, a dry cell and these magnets. Kids will really enjoy these projects.
- 【CAPTURE METAL DEBRIS】By capturing small pieces of metal, automatic transmission fluid pan magnet can prevent metal debris from clogging the oil filter or damaging the gearbox. Just place in the transmission oil pan and let the magnet do its magic, capturing small pieces of metal before they can plug the oil filter or damage the transmission. Recommends changing this spin-on filter and magnet after initial 5,000 miles of use.
- 【MAGNET CAN SAVE LIVES】 If you teach at a school where the classroom doors open out and have to be locked with a key from the outside. To make it easier to secure the doors if there is an active shooter situation, using these magnets to prevent the always locked door from closing. Thread the hole of magnet with long rope, keep rope near by your hand. If there’s an active shooter, pull the magnet from the door and the door is instantly locked.

## Questions & Answers

**Q: Why do neodymium magnets break easily?**
A: The Neodymium magnets that you use are not actually made from solid chunks of metal, but are rather made by compressing a large amount of powder into blocks through a process called sintering. This is the reason they are so brittle.

**Q: What do I need to pay attention to in the use of neodymium magnets?**
A: Neodymium magnets are not children's toys. Keep the neodymium magnet at least 25 centimeters away from electronic devices. Keep the neodymium magnet at a very safe and long distance from people with pacemakers or implantable cardiac defibrillators.

**Q: What grades of neodymium magnets are usually available?**
A: In general, neodymium magnets are available in grades ranging from N35 to N55. The higher the grade or N number, the stronger the magnetism.

**Q: How to separate two magnets correctly?**
A: The Edge Technique Utilize the edge of table or desk by positioning the magnets where they are joined and then carefully pushing the magnets apart. Be sure to quickly separate the magnets and store far enough away from each other.

I made a jig using the head of a carriage bolt on a GoPro camera with this magnet on the other side of it as a tripod mount. Just strong enough but not enough. I'll buy more but they'll be a lot more powerful than these are.

### ⭐⭐⭐⭐⭐ SUPER Strong Mangnets
*by S***Y on January 11, 2025*

Watch out, these slam together HARD and could give you a serious pinch. They easily break if you allow them to slam together, don't do that!!
