Product Description

Block NdFeB Magnet with Countersunk

 

Please kindly be noted making new molding and fixture is necessary for production of the radially magnetized magnets.
The total production cycle of samples including making molding and fixture is about *** days.
If you confirm to order, please advise the delivery address, I will calculate shipping cost and total amount for you.
BNP-8 Permanent Magnet
NdFeB ring magnets, Sizes as per drawing, Coating: Black Epoxy, Magnetized, 8 poles across diameter
Molding Cost: USD***; Fixture: USD***, Unit Price: USD***/pc
When we arrange production, we need to know the magnetization is across outer diameter or inner diameter.
If magnetize the magnets across outer diameter, the magnetic force focus on outer circumferential surface
Instead to magnetize across inner diameter, the magnetic force is concentrated in the inner circular surface.
The price is the same, but the use effect is different.
Please reference the sketch of magnetization across inner diameter and across outer diameter below
The direction of arrow is magnetization direction, please check.

Magnetized through Inside Diameter or Outside Diameter:

We don’t understand the difference between the inside diametervs outside diametermagnetization. If the ring is radially magnetized, the magnetic moment should go from the center to the outside like your drawings show. Basically, the magnetization is axially symmetric. Could you please explain in more detail the difference?
