Engineered with premium Alnico alloy for high magnetic strength and heat resistance, it is an essential demonstration tool for science classrooms, physics labs, and industrial applications.\n\nCast from a powerful alloy of Aluminum, Nickel, and Cobalt (Alnico), this U-shaped magnet features two distinct magnetic poles positioned on the same plane to create a strong, concentrated magnetic field between the ends. It comes equipped with a removable steel keeper plate spanning the poles, which protects against demagnetization and preserves magnetic power during storage. Painted in a durable gloss red finish, it provides excellent visual recognition for educational setups.\n\nHigh Magnetic Strength: Cast Alnico alloy delivers a potent magnetic field with exceptional stability and resistance to demagnetization from heat (up to 500°C).\n\nConcentrated Magnetic Field: The U-shape brings both North and South poles side-by-side, creating a dense magnetic field perfect for lifting and field line mapping experiments.\n\nIncludes Steel Keeper Bar: Comes with a soft iron\/steel keeper plate to complete the magnetic circuit during storage, ensuring long-term flux retention.\n\nDurable Painted Finish: Coated in protective, high-visibility red paint for quick identification and corrosion protection.\n\nSTEM \u0026amp; Classroom Essential: Perfect for demonstrating magnetic field lines with iron filings, polarity attraction\/repulsion, and electromagnetic induction.\n\nMaterial: Cast Alnico (Aluminum-Nickel-Cobalt Alloy)\nTemperature Resistance: Up to 500°C\nAccessories Included: Soft steel\/iron keeper plate\nApplications: Educational science demonstrations, physics labs, magnetic field mapping, industrial sorting","brand":"edumartstore","offers":[{"title":"Default Title","offer_id":47214018756796,"sku":"2","price":130.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0740\/8566\/2908\/files\/61r8DFO7jIL._SL1000.jpg?v=1785406407","url":"https:\/\/www.edumartplus.com\/products\/alnico-u-shaped-horseshoe-magnet-with-steel-keeper-plate-high-strength-educational-laboratory-physics-magnet","provider":"edumartstore","version":"1.0","type":"link"}
