2. N42SH, 70x50x25mm, NiCuNi coating, magnetized via 25mm.
3. N35SHT, 90x35x30mm. NiCuNi coating, magnetize via 30mm.

If you are interested, welcome your inquiry.
Block Magnets is one regular shape of Rare earth magnets and perment magnets.
It is always manufactured via Cutting and grinding etc. Block magnets or Rectangle magnets have the following important factors such as, Length, Width, Thicknes, Round Edge etc
.
To offer you our Block magnets price, please offer the following details:
Magnets grade: From N35 To N50, from N Serieces to UH Series.
Magnets size: Length, Width, Thickness
Magnetism direction: Which direction to oriented The north pole and south pole
Magnets coating: Nickel, Zn, Black Epoxy, Ag, Au Etc.
Quantities: More mass order quantities. More Lower the prices. Original factory.

Pick Up magnets, which are used in Disk Reading, is always small block magnets, such as 4x4x3mm.
