Large 150mm x 50mm x 25.4mm Ferrite Magnet

This ferrite block magnet measures 150mm long x 50mm wide x 25.4mm thick, providing a substantial rectangular magnetic component for industrial, technical and general-purpose applications.

Its block geometry can be incorporated into:

• Machinery
• Magnetic separation equipment
• Industrial fixtures
• Product assemblies
• Holding systems
• Educational equipment
• Research projects
• Custom magnetic systems

The 150mm x 50mm 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 called ceramic magnets, are permanent magnets manufactured from iron oxide combined with other ceramic materials.

They are widely used because they offer a practical combination of:

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

Ferrite magnets typically have a dark grey to black ceramic appearance and generally do not require a protective coating for normal corrosion resistance.

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

Ferrite Magnet for Industrial Applications

The substantial size of this ferrite block makes it suitable for incorporation into larger magnetic systems and industrial assemblies.

Potential applications include:

• Magnetic separation equipment
• Holding systems
• Machinery
• Manufacturing equipment
• Positioning systems
• Fixtures
• Product assemblies
• Custom magnetic mechanisms

For engineered applications, magnetic performance should be assessed as part of the complete magnetic circuit rather than from magnet dimensions alone.

Magnetic Separation Applications

Ferrite block magnets can be incorporated into appropriately designed magnetic separation systems used to attract ferromagnetic iron and steel contamination.

Depending on the system design, magnetic separation may be used to help capture:

• Ferrous fragments
• Iron particles
• Steel contamination
• Ferromagnetic debris

Actual separation performance depends heavily on the magnetic circuit, magnet orientation, distance from the material stream, contaminant properties and operating conditions.

This individual block magnet should not be assumed to provide a particular separation rating without testing it as part of the complete separator assembly.

Magnetisation Direction

The magnetisation direction of this 150mm x 50mm x 25.4mm ferrite block magnet has not been supplied.

Rectangular ferrite magnets can be manufactured with different magnetic pole orientations. Magnetisation direction determines which surfaces function as the principal north and south pole faces and can significantly affect performance within an assembly.

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

Magnetic Holding Performance

Actual magnetic performance depends on multiple factors, including:

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

No specific pull force or Gauss rating has been supplied for this product and these values should not be inferred solely from the magnet's dimensions.

Magnetic Attraction Decreases with Distance

Ferrite magnets generally provide their strongest practical attraction when positioned close to compatible ferromagnetic material.

Magnetic attraction decreases as the distance between the magnet and target increases.

Air gaps may be introduced by:

• Paint
• Plastic
• Adhesive
• Protective coatings
• Dirt
• Rust
• Surface irregularities

Where stronger attraction is required, unnecessary gaps between the magnet and target material should be minimised.

Direct Pull vs Shear Force

Magnetic holding performance varies depending on the direction in which a load is applied.

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

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

Practical vertical or sideways holding capacity may therefore differ significantly from ideal direct-pull performance.

Compatible Target Materials

Ferrite magnets attract ferromagnetic iron and compatible steels.

Suitable target materials may include:

• Mild steel
• Iron
• Magnetic steel
• Ferromagnetic machinery components
• Compatible steel plates

Ferrite magnets will not effectively attract:

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

Many stainless steel grades may also provide weak or negligible magnetic attraction and should be tested before use.

Ferrite vs Neodymium Block Magnets

Ferrite and Neodymium Iron Boron (NdFeB) are both permanent magnetic materials, but they offer different advantages.

Ferrite magnets are generally:

• More economical
• Naturally corrosion resistant
• Resistant to demagnetisation
• Suitable for many general-purpose and 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 equivalent magnetic performance
• Suitability for applications where installation space is restricted

A large ferrite block magnet can be a practical choice where cost, corrosion resistance and physical installation space are important considerations.

Permanent Magnetic Operation

This ferrite block is a permanent magnet and requires no external electrical power to maintain its magnetic field.

It requires:

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

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

Industrial, Manufacturing and OEM Applications

The substantial 150mm x 50mm x 25.4mm dimensions make this ferrite block magnet suitable for incorporation into larger manufactured products and engineered magnetic assemblies.

Potential users include:

• Engineers
• Equipment manufacturers
• Machinery builders
• Magnetic separator manufacturers
• Industrial fabricators
• Product designers
• Research facilities
• Educational institutions

For technical applications, the magnet should be evaluated as part of the complete magnetic and mechanical system.

Handling Large Ferrite Magnets

Ferrite is a hard and brittle ceramic material. Despite its robust appearance, it can chip, crack or fracture if subjected to impact or excessive mechanical stress.

Take care to avoid:

• Dropping the magnet
• Forceful collisions with steel
• Allowing magnets to snap together
• Excessive bending or leverage
• Concentrated mechanical loads
• Drilling, cutting or machining

Due to the substantial physical dimensions of this magnet, appropriate handling procedures should be used to reduce the risk of both magnet damage and personal injury.

Please Note

This product is a Ferrite Block Magnet measuring 150mm long x 50mm 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.

Actual magnetic performance depends on the ferrite grade, magnetisation direction, target steel thickness and composition, available contact area, air gaps, surface condition, magnet orientation and complete magnetic circuit.

Ferrite is a hard and brittle ceramic magnetic material. Avoid drilling, cutting, machining, impact and uncontrolled collisions.

This magnet should not be treated as certified lifting equipment or assigned a safe working load unless it has been incorporated into an appropriately designed, tested and rated system.

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