Making a magnetic bracelet is a straightforward craft project that requires magnetic beads or spacers, stringing material, and a clasp. You can assemble one in under an hour with minimal tools. The key decisions are choosing the right type of magnet, picking a stringing method that holds up to daily wear, and selecting a clasp strong enough to keep the bracelet on your wrist.
Choosing Your Magnetic Beads
The two most common magnet types used in bracelets are hematite and neodymium, and they differ dramatically in strength. Hematite is a naturally occurring iron oxide mineral with moderate, weak magnetism. It’s inexpensive, widely available in bead form (rounds, barrels, ovals), and has a distinctive dark metallic sheen. Hematite beads are easy to work with because their weak pull won’t cause them to snap together and pinch your fingers during assembly.
Neodymium magnets are the strongest commercial magnets available. They’re significantly more powerful than hematite, which means fewer beads can produce a stronger magnetic field. Neodymium beads are typically smaller, silver-toned, and heavier for their size. They require more care during assembly because they attract each other forcefully and can chip if they collide. For a bracelet, small neodymium disc beads (6mm to 8mm) work well as spacers between decorative beads.
You can also combine magnetic beads with non-magnetic gemstone, glass, or metal beads. This lets you control the look of the bracelet while still incorporating magnets at regular intervals.
Other Materials You’ll Need
Beyond the beads themselves, gather these supplies before you start:
- Stringing material: Stretch cord (0.7mm to 1mm elastic) is the simplest option for beginners since it eliminates the need for a clasp. For a more polished look, use stainless steel beading wire (0.018″ or 0.024″ gauge), which resists kinking and holds up well against sweat.
- Clasp: A magnetic clasp is a natural fit. Standard round magnetic clasps have a pull force of 350 to 600 grams, which works for lightweight bead bracelets. If your bracelet is heavier (using large stone beads or thick metal links), go with a barrel-style clasp with a silicone gasket rated at 700 to 1,100 grams of pull force. Anything below 300 grams risks the bracelet falling off during normal movement.
- Crimp beads and crimp covers: If using beading wire, you’ll need crimp beads to secure the wire to the clasp. Crimp covers hide the crimped bead for a cleaner finish.
- Spacer beads: Small non-magnetic metal or silicone beads placed between magnetic beads prevent them from scratching each other and add visual interest.
- Wire cutters and crimping pliers: Essential if you’re using beading wire. Not needed for stretch cord designs.
Step-by-Step Assembly With Stretch Cord
This is the easiest method, ideal for a first project. Measure your wrist with a flexible tape measure or a strip of paper, then add about half an inch for comfortable fit. Cut a piece of stretch cord about 4 inches longer than your wrist measurement to give yourself room to tie the knot.
Lay out your beads in the pattern you want before stringing. If you’re alternating magnetic and decorative beads, arrange them on a bead board or towel so they don’t roll. A common pattern is one magnetic bead followed by two or three decorative beads, repeated around the full length.
Thread the beads onto the cord. When you reach the end, tie a surgeon’s knot (a square knot with an extra pass on the first loop) to lock the elastic securely. Pull the knot tight, apply a tiny drop of jewelry glue or clear nail polish to the knot, and let it dry for a few minutes. Trim the excess cord and slide the knot inside the nearest bead to hide it.
Step-by-Step Assembly With Beading Wire
Cut your beading wire about 4 inches longer than your wrist measurement. Thread one crimp bead onto the wire, then loop the wire through one half of your magnetic clasp. Pass the wire tail back through the crimp bead, creating a small loop around the clasp ring. Use crimping pliers to flatten the crimp bead firmly. Trim the short wire tail close to the crimp.
Now string your beads in your chosen pattern. The first bead or two should slide over both the main wire and the short trimmed tail, hiding it inside. Continue stringing until you reach your target length.
To finish the other end, thread a crimp bead, loop through the second half of the clasp, pass the wire back through the crimp bead and through one or two beads, then crimp. Trim the excess wire. If you want a polished look, slide a crimp cover over each crimp bead and gently squeeze it closed with pliers so it resembles a round metal bead.
Protecting Your Magnets From Corrosion
Neodymium magnets corrode quickly when exposed to moisture, sweat, and skin oils unless they’re coated. Most neodymium beads sold for jewelry come with a nickel-copper-nickel triple-layer coating, which provides good corrosion protection and a shiny finish. Gold-coated neodymium beads resist tarnish even better and look more like fine jewelry. Epoxy-coated magnets offer the strongest moisture resistance and come in multiple colors, though they have a matte, slightly plastic appearance.
If you’re buying uncoated neodymium discs (common in craft supply packs), you can seal them yourself with a thin coat of clear nail polish or a spray-on clear lacquer before stringing. Two coats, dried fully between applications, will add a reasonable moisture barrier. Hematite beads are more naturally resistant to corrosion and generally don’t need additional sealing.
Avoiding Skin Reactions
Nickel allergy is the most common concern with magnetic bracelets, since many magnetic beads and clasps contain nickel in their coating or base metal. If you or the person you’re making the bracelet for has sensitive skin, choose beads and clasps made from titanium, surgical-grade stainless steel, sterling silver, or 18-karat gold or higher. Gold-coated neodymium beads also work, as the gold layer prevents nickel contact.
For a quick fix on components you’ve already purchased, painting the skin-contact surfaces with a clear barrier product (like Nickel Guard) or two coats of clear nail polish creates a protective layer. This wears off over time, so you’ll need to reapply every few weeks with regular wear.
Safety Considerations
Magnetic bracelets pose a real risk to anyone with an implanted medical device. The FDA recommends keeping magnets at least six inches (15 centimeters) away from pacemakers, cardiac defibrillators, and insulin pumps. Strong magnets can cause these devices to switch into a safe mode, suspending normal operations. A cardiac defibrillator, for instance, may fail to detect dangerous heart rhythms when a magnet is nearby. If you’re making a bracelet as a gift, make sure the recipient doesn’t have any implanted devices.
Neodymium magnets also pinch hard when they snap together. During assembly, keep them separated until you’re ready to string them, and keep them away from small children, who could swallow them. Two or more swallowed magnets can attract through intestinal walls and cause serious internal injuries.
Does the Magnetic Strength Matter?
If you’re making a magnetic bracelet for its look and feel, any magnetic bead will work. If you’re hoping for therapeutic benefits, the clinical evidence is limited. A review of randomized controlled trials found that magnetic therapy showed some effect on muscle pain, particularly at myofascial trigger points (the tight, tender “knots” in muscles). For other types of pain, including joint pain and general soreness, the evidence did not support magnetic therapy as an effective treatment. The results across studies were inconsistent, and no standard magnetic strength has been established as therapeutic.
Commercial “therapy” bracelets typically advertise strength in gauss (a measure of magnetic field intensity), but there’s no agreed-upon gauss rating that produces reliable health benefits. If pain relief is your goal, treat a magnetic bracelet as a complement to proven approaches rather than a standalone solution.
