20pcs N35 4mm x 9mm Neodymium Rod Magnets Strong Rare Earth Cylinder Magnets Home Depot

N35 4mmx9mm Neodymium Rod Magnets Strong Rare Earth Cylinder Magnets Home Depot Amazon

Our 4mm diameter Neodymium rod magnets are some of the smallest in our rod magnet range and produce an astonishing 0.5kg pull for their size. These particular magnets are favoured among craft enthusiasts and model makers but they also have many uses in engineering, manufacturing and technology where small size and maximum strength are required. What’s more, because of their resistance to demagnetisation they are ideal for creating a shock-absorbing or damping effect when used to repel other magnets.

WARNING!!!
Strong magnets should Keep away from Ironware and some easily magnetized iron products, such as monitors, bank cards, computers, televisions, mobile phones and other.
Magnets might affect water meter ,electric meter, gas meter and some metering equipment exist some inaccurate affect (Such as : if magnets placed near the meter, the meter will slow down)
These magnets are very powerful which should be handled with great care. Without parents supervised do not allow children to playing magnets as they could get injured. Especially pay attention to the small magnets , please place in somewhere children can’t reach place.
