Teguブロックがくっつかない？磁石の問題を解決

Tegu blocks that won't connect usually have a polarity mismatch, a blocked mating face, or a damaged magnet. Run this quick diagnosis before you replace anything.
Quick answer
Most Tegu blocks that won't stick have a polarity mismatch, not a broken magnet. Flip the piece 180 degrees and press it against a different face before you assume anything is wrong. If it still refuses to hold on every face, check the mating surfaces for debris or a pushed-in magnet, and only then treat it as a repair or replacement case.
Rule out polarity before you blame the magnet
Tegu magnets sit inside the wood with a fixed north-south orientation, so a piece that repels on one face may grip firmly on the opposite face or on a different block entirely. Rotating a block in your hand and testing each face takes seconds and eliminates the most common false alarm. If a piece connects to some blocks but pushes away from others, the magnet is working exactly as designed.
- Rotate the piece 180 degrees and retest the same joint.
- Test the same two pieces on a different face before concluding anything.
- Try a third block as a control to see whether the problem follows one piece.
Check the mating faces for what's blocking contact
Magnets only feel each other across a small gap, so anything sitting between two faces weakens or kills the connection. Crayon wax, sticky snack residue, a sliver of play dough, or a swollen spot from a recent wipe-down can all interfere. Wipe both faces with a barely damp cloth and let them dry completely before retesting, since trapped moisture between flat surfaces can also reduce grip.
- Look for crumbs, sand, or dried food in the recessed magnet pockets.
- Check for a magnet sitting proud of the wood surface or pushed below it.
- Let blocks air-dry fully after cleaning before judging the connection.
Decide when to stop troubleshooting
If a piece fails on every face, against every block, after cleaning and drying, the magnet has likely shifted or lost strength and no amount of technique will fix it. At that point, stop testing and either set the piece aside for a repair or contact the retailer about a replacement. Continuing to force mismatched pieces together stresses the wood and can widen the magnet pocket.
- One failing face: normal polarity, no action needed.
- One failing piece against all others: inspect or repair that piece.
- Every piece failing against every other piece: check for a batch or storage issue.
Symptom-to-fix diagnosis
- Blocks push apart instead of pulling together: Two magnets are meeting with matching poles. Rotate one piece 180 degrees or move it to a different face of the other block. If the joint holds after rotating, nothing is broken.
- Blocks hold on one side but slide off on another: This is normal polarity behavior, not a defect. Use the faces that grip, or rebuild the joint so the gripping faces meet. Stop here unless the piece fails on every face.
- Connection feels weak or lets go under light pressure: Clean both mating faces, remove debris from the magnet pockets, and dry the wood fully before retesting. If grip returns, the cause was surface contamination.
- One piece never connects to anything: The magnet has likely shifted or weakened. Compare it against a known-good block from the same set to confirm. Set it aside for repair or ask the retailer about a replacement.
- Every block in the set feels weak at once: Look at storage and cleaning habits: repeated soaking, heat, or drops can affect several pieces together. Change how you clean and store the set, then retest before buying replacements.
Sets worth knowing about
- Pip Magnetic Wooden Blocks Sticky Monsters, 8 pieces: Pip Magnetic Wooden Blocks Sticky Monsters, 8 pieces, includes 2 Short Planks, 4 Monster Horns, 1 Pip Horso, and 1 Pip Tail, and is fully compatible with all other Tegu blocks. A small set like this is the cheapest way to test whether a problem follows one block or affects your whole collection, since every piece is designed to connect across sets.
- Beans & Tumtum Magnetic Wooden Blocks Sticky Monsters, 30 pieces: Beans & Tumtum Magnetic Wooden Blocks Sticky Monsters, 30 pieces, includes 30 pieces in 11 shapes such as 2 Short Planks and 2 Long Planks. With more shapes and more mating faces, a larger set gives you plenty of alternate connections to test before you conclude that a magnet has failed.
- Daredevil Magnetic Wooden Blocks Stunt Team, 12 pieces: Daredevil Magnetic Wooden Blocks Stunt Team, 12 pieces, is a vehicle-focused set whose members work with any other creation you make. Vehicle builds put repeated stress on a few joints, so if blocks loosen only during fast play, the cause is usually play style rather than a weak magnet.
