Block Neodymium N35 Rare Earth Magnets – 60 x 10 x 5mm, N35 “KitKag”
Have a break, have a KitKag!
While this longish looking block of a magnet may look remotely similar to a chocolate bar, we caution against taking a bite out of it as the first thing to break maybe your pearly white teeth.
Long rectangle neodymium magnets N35, a.k.a. rare earth magnets are good for projects where magnetic holding force are needed in long, narrow spaces.
Although all neodymium magnets share the same characteristic of strong magnetic attraction force and brittle nature, which sometimes causes them to break on high impact collision with another magnet or even metal objects, some shapes and sizes are more prone to breakage than others. This particularly long and rather slim shaped rectangle rare earth magnet at N35 grade is among the type that breaks quite easily. The visible reason that causes this magnet to break on collision is its length with a narrow profile. Its thickness of 5mm means that this magnet has relatively strong pull force compared to other magnets with 2mm or less thickness. Hence, do take care when separating or handling neodymium magnets, always holding each piece firmly such that the separated piece does not accidentally slip from your hands and “jump” back to collide with the remaining stack of magnets.
The magnet tendency to break is greatly reduced once the magnet is installed/secured/glued to a base or better still, covered with duct tape/fabric/thin cardboard etc as these will soften the impact by reducing/absorbing some of the forces.
Attaching a piece of ferrous metal to any magnet increases the magnetic field/strength on the opposite side of the magnet as the ferrous metal will deflect the magnetic field on its side and channel it to the other side. An example: If you attached a sheet of ferrous metal to the north pole of a magnet, the strength of its south pole will be increased.
A simple experiment you can try:
Hold a piece of magnet and try to lift a metal object that is slightly too heavy for the magnet to pick up.
Next, attach the same magnet to a thick piece of ferrous metal and try lifting the same object again.
Below: Stacking 4 pieces of 50cents coins on top of each other edges, thanks to the magnetic holding strength of neodymium magnets, it can be accomplished quite easily.
Below: This KitKag bar doesn’t melt on your finger, and is way stronger than the chocolate bar version.
