Hall Sensor 4x0.5 4x1 4x3 4x2 5x0. 5x1 5x2 mm Circular Disc Neodymium NEW Art Craft Connection Magnets(4x4mm 60pcs N52)

High quality materials and processes: Made of NdFeB neodymium iron boron material, the surface is electroplated with three layers of nickel, copper, and nickel, smooth and free of burrs. After adsorption, it can be removed without scratching the surface of refrigerators, whiteboards, etc.Stability performance: The maximum temperature tolerance is 80 ℃ (176 ℉), the magnetic force is strong and long-lasting, and small defects do not affect normal use.PrecautionsThe texture of the magnet is brittle, so it should be handled gently to avoid collision and damage.Children under 8 years old are prohibited from contact to prevent accidental ingestion.widely usedCovering multiple fields such as acoustics (sound, microphone), electronics (relays, sensors), electrical (motors, generators), mechanical equipment (magnetic separators, magnetic hoists), medical (MRI equipment), gift packaging, door and window magnetic attraction, toy making, etc.

• 【Scratch-Free Technology】 - Each of our ultra-strong neodymium magnets features a smooth surface that can be easily removed without leaving scratches on refrigerators or office boards. No need to worry about potential damage to your fridge or new table. Perfect for use as dry-erase board magnets, pin magnets, whiteboard magnets, map magnets, memo or photo boards, crafts, DIY materials, and more.
• 【 High quality coating 】 The magnetic strip is coated with three layers of nickel, copper, and nickel, providing corrosion resistance and a smooth, glossy, rust proof surface. This ensures that our refrigerator uses neodymium magnets for long-lasting durability
• DIY projects and scientific experiments include refrigerator magnets, shower doors, work or office spaces, scientific purposes, art and crafts, or school classrooms.
• 【 Warning 】 Magnets are very fragile and should not collide with other metal objects (including another magnet), so be careful when trying to separate them!
