Grtard 20 Pack Ceramic Disc Magnets 0.71in 🧲
Product description
This pack of small ceramic disc magnets is practical for crafts, classroom activities and simple science projects, offering a compact way to attach items to metal surfaces or to explore magnetic interactions. The set combines thin ferrite discs with adhesive backing, making it straightforward to mount photos, lightweight decorations or experiment components around the home or workshop.
Key Points
The set contains 20 round ceramic magnets with adhesive pads included for attaching to non-metal surfaces. Each disc has a bevelled edge to reduce surface scratching and a small dot marking the north pole, which helps when demonstrating polarity and field direction. According to the manufacturer, the ferrite material resists demagnetisation and corrosion, which supports repeated handling in craft and educational settings. Note that these are strong magnets and are labelled for ages 15 and over for safety reasons.
Technical Specifications
Name: Grtard 20 Pack Ceramic Magnets
- Diameter: 18 mm (0.71 inch)
- Thickness: 3 mm (0.12 inch)
- Quantity: 20 pieces with 20 adhesive pads
- Material: Ferrite (ceramic) magnet
Usage Recommendations
For craft projects, peel and stick the supplied adhesive backing onto wood, plastic or card before placing the magnet. For experiments that show attraction and repulsion, keep a clear workspace and separate individual discs to observe pole interactions. When used on whiteboards or refrigerators, apply gentle pressure to ensure the adhesive makes full contact. Handle with care if using near magnetic storage or medical devices, and keep away from children under 15.
Positive Aspects
The slim profile of these discs makes them easy to conceal behind photos or lightweight fixtures, while the bevelled edges reduce the risk of scratching surfaces. The small north-pole indicator simplifies demonstrations of polarity when teaching basic magnetism. Because the magnets are ferrite, they are less likely to corrode in normal indoor use, which helps maintain performance over time. Consider that their holding strength is modest compared with rare-earth magnets, so they are best for light-duty holding and educational purposes rather than heavy fastenings.
