If you’ve ever found yourself in a complicated DIY home project, you know how frustrating working with tiny screws and componentry can be. The smaller the supplies, the higher the level of required dexterity—and the easier it is to lose things in the process. 

That’s when a magnetizer/demagnetizer tool can become so valuable. These innovative devices are capable of turning ferromagnetic tools like screwdrivers and wrenches into “magnets” themselves, giving you more control over screws, nuts, and bolts.

But how does a magnetize and demagnetize tool work—and is it safe to keep inside your home near your kids and pets? Read our full blog to learn more!

How Does A Magnetizer/Demagnetizer Work?

Look closely at one of these tools, and you’ll notice it has two distinct sides: one for magnetizing and one for demagnetizing. Each side has a unique design to achieve a similarly unique objective. 

How the Magnetizer Works

The magnetize side of the tool is outlined by internal permanent magnets that are precisely positioned so when a ferromagnetic object (like a screwdriver) passes through at a controlled speed, its magnetic domains are realigned. As a result, the object becomes magnetic!

How the Demagnetizer Works

The demagnetize side of the tool is designed to decrease an object’s magnetism. By misaligning its magnetic field, the object gradually loses its magnetic force. As we’ll explore in a moment, this can make your tool safer to use with sensitive electronics. 

Why Should You Use A Magnetizer/Demagnetizer Tool?

Effectively working with a magnetizer/demagnetizer tool requires understanding their unique advantages around the home. Here’s how each one stands out: 

When To Use A Magnetizer Tool

A magnetizer tool can make you more efficient around the house across a variety of situations, including: 

  1. You want a better “grip.” Don’t let tiny screws and other parts roll all over the place. A magnetized tip keeps everything in place. 
  2. You need more precision. Working with tiny screws is tough! A magnetized tip gives you more control.

When to Use A Demagnetizer Tool

A demagnetizer tool can be handy in a few different DIY scenarios, including:

  1. You’re working with sensitive electronics. If you like working on computers or other delicate electronics, a magnetized screwdriver or similar tool could actually hurt your componentry. 
  2. You’re working in tight spaces. If you’re working in tight quarters with other metal debris, a magnetized tip to your tools can actually get in the way. 
  3. You don’t want magnetism. Sometimes, a screwdriver or similar tool with a magnetic tip can actually make things more challenging, especially when the tip attracts other small objects or moves screws off to the side so they dangle from below. You can correct for this by removing magnetism altogether with a demagnetize tool.

Safety Warning: Magnets can be dangerous. Neodymium magnets, especially, must be handled with care to avoid personal injury and damage to the magnets. Fingers and other body parts can get severely pinched between two attracting magnets. Bones can be broken by larger magnets. Visit our Magnet Safety page to learn more.
