Magnetizer and Demagnetizer iFixit EU145029-3 by iFixit

iFixit Magnetizer and Demagnetizer EU145029-3 by iFixit is a compact handheld tool designed to change the magnetic state of metal screwdriver bits and small tools. It enables technicians to magnetize tips for improved retention of screws or to demagnetize them when magnetic fields could interfere with delicate electronics or precision assemblies. The tool is suitable for workshop benches, service carts and field repairs where quick switching between magnetized and demagnetized tips is required.

Advantages

The device offers a simple, two-mode operation that lets you magnetize or demagnetize metal bits quickly without additional equipment. Its small footprint makes it easy to keep on a workbench or in a technician’s kit, and it works with a wide range of steel and iron tips used in electronics repair and general maintenance. The controlled magnetizing process improves screw pick-up and retention, reducing drops, while the demagnetizing option helps prevent magnetic interference with sensitive components.

Suitable for

• Electronics repair and microelectronics assembly
• Precision screwdriver work and small hardware assembly
• General maintenance where temporary magnetization of bits is useful
• Field service and on-site repairs requiring quick switching of bit magnetization

When it may not be suitable

This tool is not intended for magnetizing large tools, heavy-duty power-driver bits, or non-ferrous materials such as brass, copper or stainless steels with low magnetic permeability. It also should not be used near magnetic storage media or devices that are highly sensitive to magnetic fields unless the demagnetize function is applied and proper precautions are taken.

Key specifications

• Function: magnetize and demagnetize metal screwdriver bits and small ferrous tools
• Form factor: handheld, compact housing suitable for bench or kit storage
• Compatibility: works with steel and iron bits commonly used in precision and electronics repair
• Operation: two-mode operation for magnetizing or demagnetizing

How to use

To magnetize a screwdriver bit, insert the clean, dry metal tip into the magnetizing slot and move it through the area as recommended by the manufacturer to induce a magnetic field; test retention on a screw and repeat if a stronger effect is required. To demagnetize, insert the bit into the demagnetizing slot and withdraw it according to the device’s instructions, or move it through the demagnetizing area to reduce residual magnetism. Always follow safe handling practices and ensure the tool and bits are free of debris before use.

What to consider before purchase

• Material compatibility: effective on ferrous metals (steel, iron) but not on non-magnetic alloys
• Intended use: designed for small bits and tools rather than large industrial drivers
• Work environment: avoid use near magnetically sensitive media or devices unless demagnetized
• Storage: compact size allows easy storage in toolkits or on workbenches

Usage recommendations

Use the magnetize function when you need improved screw pick-up and retention during assembly. Use the demagnetize function before working near magnetic sensors, storage media or delicate components. Keep bits clean and inspect magnetization strength on a spare fastener before working on critical devices.
