8103 – Ceramic VIII Ferrite Block Magnet 3 × 2 × 1/2 in

SKU 8103 is a Ceramic VIII ferrite block magnet measuring 3 × 2 × 1/2 inches. It is magnetized through the 1/2-inch thickness, placing the poles on the two broad 3 × 2-inch faces. Its rectangular geometry suits industrial holding, separation, fixtures, motor components, prototypes, and production assemblies where package space allows the use of ferrite. Ceramic magnets offer an economical material option with natural corrosion resistance.

Design notes for this ceramic block magnet

Confirm the target-steel thickness, contact area, operating air gap, mounting method, and load direction in the final assembly. Ferrite is hard and brittle, so avoid impact, uneven clamping, and excessive mechanical stress. Provide suitable support and controlled installation to protect the magnet during assembly.

The listed 18.41 lb pull force is a comparison value under defined contact conditions, not a guaranteed safe working load. Air gaps, surface finish, thin target steel, misalignment, and shear or peel loading can reduce usable force. Review the complete magnetic circuit and thermal conditions when evaluating the listed temperature limit.

Use the magnet pull force calculator for preliminary screening, review the temperature derating calculator, browse ferrite and ceramic magnets, or submit the magnet RFQ builder for production quantities or custom requirements.
