They are easy to recognise due to their dark graphite grey colour, they are very sluggish, they do not rust and protective coating not required. They have adequate resistance to demagnetization and can operate at temperatures up to 180 degrees Celsius. Review: Terrible magnets, do not purchase. Review: Ich habe diese Magnete benötigt um bei einem Mähroboter die Pole der verbauten Magnete zu finden. Dafür sind sie gut geeignet, weil ich feststellen konnte das einer der Magnete falsch herum eingebaut war. Das war der Grund warum der Mäher oft in Störung ging. Die Kraft der Magnete ist aber ziehmlich gering, so das sie für Befestigungsaufgaben nicht geeignet sind. Aber zum Prüfen von Sensoren usw. sind sie sehr gut geeignet, darum gibt es eine Empfehlung von mir. ## Features - Supplied in first4magnets labelled packaging, with branded booklet for safe handling - Made from high quality ferrite material ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01EVO1D5Q | | Best Sellers Rank | #126,610 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #166 in Industrial Magnets | | Item model number | FB160450-4 | | Manufacturer | first4magnets | | Product Dimensions | 1.6 x 0.41 x 5 cm; 20 g | ## Product Details - **Brand:** Magnet Expert - **Colour:** silver - **Material:** Metal - **Product dimensions:** 16L x 4W x 50Th millimeters - **Shape:** Rectangular ## Images ![First4magnets™ FB160450-5 16 x 4 x 50 mm Long Ferrite Bar Magnet with North-South & Identified (Pack of 4), Metal, Silver, 25 x 10 x 3 cm, 4 Units - Image 1](https://m.media-amazon.com/images/I/61XYBbURh-L.jpg) ![First4magnets™ FB160450-5 16 x 4 x 50 mm Long Ferrite Bar Magnet with North-South & Identified (Pack of 4), Metal, Silver, 25 x 10 x 3 cm, 4 Units - Image 2](https://m.media-amazon.com/images/I/61LTaAjLRkL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐ Review *by S***Y on 7 October 2025* Terrible magnets, do not purchase. ### ⭐⭐⭐⭐⭐ Review *by M***N on 4 April 2024* Ich habe diese Magnete benötigt um bei einem Mähroboter die Pole der verbauten Magnete zu finden.

They are extremely weak, and it turns out they are just pieces of steel with a small round magnet embedded in each end. Totally unusable for any application you might need bar magnets for. What’s more, one of them was snapped in half inside the package. Worthless. ## Frequently Bought Together - Ferrite Bar Magnet with North & South Identified for Science, Education, Experiments, Students, and Teachers - 16mm x 4mm x 50mm long - Pack of 4 - Iron Filings for Science, Education, Experiments, Students, and Teachers - 80g - Traditional Alnico Horseshoe Magnet for Science, Education, Experiments, Students, and Teachers - 1kg Pull - 75mm x 39mm x 8mm --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/629802973-first4magnets-fb160450-5-16-x-4-x-50-mm-long](https://www.desertcart.vn/products/629802973-first4magnets-fb160450-5-16-x-4-x-50-mm-long) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-16*
