Large 150mm x 100mm x 25.4mm Ferrite Block Magnet

This ferrite magnet measures:

• Length: 150mm
• Width: 100mm
• Thickness: 25.4mm

Its substantial rectangular format provides a large magnetic component for applications where compact dimensions are less important than broad surface area and practical permanent magnetic performance.

The block geometry can be incorporated into:

• Industrial machinery
• Magnetic assemblies
• Separation equipment
• Fixtures
• Research apparatus
• Educational equipment
• Custom manufactured systems

The 150mm x 100mm x 25.4mm dimensions describe the physical size of the magnet and should not be interpreted as a pull-force or safe load-capacity rating.

Ferrite Ceramic Permanent Magnet

Ferrite magnets, also commonly known as ceramic magnets, are permanent magnets manufactured using iron oxide combined with other ceramic materials.

Ferrite is widely used in industrial and general-purpose magnetic applications because it provides a practical combination of:

• Cost-effective magnetic performance
• Good resistance to demagnetisation
• Good natural corrosion resistance
• Permanent magnetic operation
• Suitability for a broad range of applications

Ferrite magnetic material typically has a dark grey to black ceramic appearance and generally does not require additional protective plating for normal corrosion resistance.

The specific ferrite grade of this block magnet has not been supplied and should not be assumed.

Magnetic Separation Applications

Large ferrite block magnets can be incorporated into appropriately designed magnetic separation and ferrous contamination control systems.

Depending on the complete magnetic circuit, installation and operating conditions, ferrite magnets may assist in attracting ferromagnetic contaminants such as:

• Iron particles
• Steel fragments
• Ferrous metal pieces
• Magnetic manufacturing debris
• Compatible tramp metal

Potential installations may include equipment handling suitable:

• Powders
• Granules
• Bulk materials
• Manufacturing feedstocks
• Free-flowing materials

The suitability of this individual magnet for a magnetic separator depends on the complete system design. The magnet alone should not be assumed to provide a particular separation efficiency or capture distance.

How Magnetic Separation Works

Magnetic separation uses a magnetic field to attract ferromagnetic contamination from material passing through or near a magnetic separation system.

Performance depends on factors including:

• Ferrite grade
• Magnetic circuit design
• Distance between the contaminant and magnet
• Contaminant size
• Contaminant shape
• Ferromagnetic properties
• Material flow rate
• Product depth
• Installation geometry
• Orientation of the magnet

Magnetic attraction decreases significantly as the distance from the magnetic surface increases.

For this reason, effective separator design generally aims to bring potential ferrous contaminants sufficiently close to the magnetic field.

Materials Magnetic Separation Can Capture

Ferrite magnets attract ferromagnetic materials, particularly iron and compatible steels.

Potential contaminants may include:

• Iron fragments
• Mild steel
• Steel particles
• Ferrous fasteners
• Magnetic swarf
• Compatible steel contamination

Materials such as the following are not effectively captured by conventional permanent magnetic separation:

• Aluminium
• Copper
• Brass
• Plastic
• Timber
• Glass

Many stainless steel grades may also be weakly magnetic or non-magnetic and should not be assumed to be effectively captured.

Magnetic Holding and Positioning

In addition to separation applications, this large ferrite block magnet may be incorporated into appropriately designed holding and positioning systems.

Potential uses include:

• Industrial fixtures
• Positioning equipment
• Machinery
• Manufacturing assemblies
• Custom magnetic devices
• Research equipment

Practical holding performance depends on the complete magnetic circuit and mechanical design.

Magnetisation Direction

The magnetisation direction of this 150mm x 100mm x 25.4mm ferrite block magnet has not been supplied.

Block magnets can be manufactured with different magnetic pole orientations. The north and south poles may therefore be positioned on different pairs of opposing faces depending on the magnet's design.

Magnetisation direction can significantly affect:

• Magnetic separation performance
• Working face selection
• Holding performance
• Interaction with other magnets
• Magnetic circuit design

Where pole orientation is important, the magnetisation direction should be confirmed before installation.

Magnetic Performance

Actual magnetic performance depends on factors including:

• Ferrite grade
• Magnetisation direction
• Magnetic circuit design
• Target steel thickness
• Target steel composition
• Available contact area
• Air gaps
• Surface condition
• Magnet orientation
• Load direction

No specific pull force or Gauss rating has been supplied for this product and these values should not be inferred solely from its large physical dimensions.

A larger magnet is not automatically suitable for lifting a corresponding amount of weight.

Direct Pull vs Shear Force

For magnetic holding applications, performance varies according to the direction of the applied load.

Direct pull occurs when force attempts to separate the magnet perpendicular to a ferromagnetic target surface.

Shear force occurs when the load acts parallel to the target and encourages the magnet to slide.

Practical vertical or sideways holding performance can therefore be considerably lower than ideal direct-pull performance.

Magnetic Attraction and Air Gaps

Ferrite magnets generally perform best when positioned close to compatible ferromagnetic material.

Magnetic performance can be reduced by gaps created by:

• Paint
• Plastic
• Adhesive
• Protective coatings
• Dirt
• Rust
• Surface irregularities
• Physical separation from the target

This is particularly important in magnetic separation applications, where increasing the distance between a contaminant and the magnetic surface can significantly reduce attraction.

Ferrite vs Neodymium Block Magnets

Ferrite and Neodymium Iron Boron (NdFeB) are both permanent magnetic materials but provide different characteristics.

Ferrite magnets are generally:

• More economical
• Naturally corrosion resistant
• Resistant to demagnetisation
• Suitable for large-format magnetic components
• Widely used in general industrial applications
• Lower in magnetic strength relative to size than neodymium

Neodymium magnets generally provide:

• Much higher magnetic strength relative to size
• More compact dimensions for higher-performance applications
• Strong magnetic fields from comparatively small components

Ferrite can be an excellent choice where cost-effectiveness, corrosion resistance and a larger physical magnetic component are appropriate for the application.

Permanent Magnetic Operation

This ferrite block is a permanent magnet and requires no external electrical supply.

It requires:

• No electricity
• No batteries
• No charging
• No electrical wiring

The magnetic field remains continuously active during normal use, storage and handling.

Handling Large Ferrite Block Magnets

Ferrite is a hard and brittle ceramic material, and a block magnet of this size should be handled carefully.

Large ferrite magnets can be damaged by impact, bending stress or uncontrolled collisions.

Avoid:

• Dropping the magnet
• Allowing magnets to collide forcefully
• Impact with steel surfaces
• Concentrated point loads
• Excessive clamping pressure
• Drilling
• Cutting
• Conventional machining

Appropriate handling methods should be used to support the magnet's size and weight during installation and transport.

Please Note

This product is a Ferrite Block Magnet measuring 150mm long x 100mm wide x 25.4mm thick.

No specific ferrite grade, pull force, Gauss rating, magnetisation direction, dimensional tolerance or maximum operating temperature has been supplied and these specifications should not be assumed.

For magnetic separation applications, actual capture performance depends on the complete magnetic circuit, contaminant material, contaminant size and shape, distance from the magnetic surface, product flow, installation geometry and operating conditions.

The magnet should not be considered certified lifting equipment or used as the sole means of supporting a hazardous load without an appropriately engineered system.

Ferrite is a hard and brittle ceramic material. Avoid drilling, cutting, machining, impact, force-fitting and excessive mechanical pressure.

Keep magnets away from small children and sensitive magnetic or electronic equipment.
