What adhesive should I use on neodymium magnets?

adhesive neodymium magnets - As a senior magnet manufacturer, we met some customers who consulted us adhesive for rare earth magnet. Magnets for motors, magnet for loudspeakers and magnet with plastic all need adhesive. Questions like: 1. What adhesive should I use on neodymium magnets? 2. Best adhesive for permanent magnets? 3. Best glue or method for attaching magnets? First, you should get to know your magnet well. 1.Strong Magnetic force, if possible, make a hole to fix magnet 2.Usually Ni coating, very smooth, if possible, get them rough enough 3.Max working temp. (Different grades have different working temp.) , with high temp., magnet will demagnetize. Second, to choose an adhesive, you should pay more attention to the application environment. Different adhesive, the application is different. E.g. Temp. Humidity, Oil condition and so on. You [...]

Large Magnets and Small Magnets Safety Precautions

Large Magnets and Small Magnets Safety Precautions Large Magnets Warning Big magnets have a very strong attractive force. Unsafe handling could cause jamming of fingers or skin in between magnets. This may lead to contusions and bruises. Larger magnets (more than 0.5 lbs) can easily crush fingers and break bones.

(sound is not “moving air” it is propagating pressure fluctuations.) The Dustcap (optional) – located at the center of the cone and [...]
