Magnetpro Multipurpose Switch Magnet, 660 LB Pulling Force, On/Off Magnet for Lifting, Machining & Welding Positioning, Liquid Filtration, Automation, Metal Separation

Great mechanical switchable magnet. Exceptionally strong when switched on and completely inert when not. Has a good holding capacity. Used a few of them integrated into theatre sets where items have to fall off a wall on cue, and works perfectly for this purpose where budget or safety means an electromagnet isn't suitable for the same purpose.

I found this interesting how it turns on and off. The magnet unit is very heavy but small enough to manage. It would fit in a decent size tool box to take with you. The magnet is activated easily by pressing and turning the lever which then engages the magnet on whatever surface you are on. I have tried it on various pieces and it’s only as strong as the material you are fixing to. If it’s thin sheet steel it doesn’t hold strongly. For 3mm thick steel it doesn’t take a massive amount of force to remove it.

Great bit of kit for me to use as a temp handle Really strong adhesion to metal plates

Unable to review as item was faulty and I could not get the handle to turn. It is a substantial lump of steel - very heavy and well finished - but unusable.

That's neat looking magnet which, when in use, it's really powerful. First of all, we need to screw in the handle. Then if we want to 'activate' the magnet, we need to press the handle down and then rotate it 180⁰, just as the arrows shows on the magnet. The magnet's force starts to work and ypu could feel that it attaches to the metal with huge power. I've tested it on fridge and without deactivating the magnet (turning the handle to off position), I literally couldn't remove it from the surface, that strong it is. The magnet looks nice and it has predrilled holes on sides in case you need to attach some holding frame to it, if more than one magnet you are going to use at once. This is expensive piece of gear but I'm sure we will find many uses of it over the time. Can recommend it.

This is a very strong magnet. It can easily lift the stated weight. It works best when used against a flat metal surface, it's a bit less secure if the magnet is not completely face to face with the metal it is trying to connect to. The magnet is secured and released by a mechanical movement of a sleeve that pushes the magnet away from the metallic item. To use this, you have to turn a handle at the top 90 degrees. This is quite difficult to do, the handle is not comfortable to hold and the movement is difficult to do and notchy. Whilst it's a mechanical process, it is not a fluid one. Overall, this is a really strong magnet and scores positively in that respect, but the handle mechanism lets it down.

Highly effective fishing magnet! The fishing magnet I purchased exceeded my expectations in terms of performance and durability. With its strong magnetic force, it effortlessly retrieves metallic objects from water bodies such as lakes, rivers, and ponds. The construction is robust, ensuring that the magnet withstands the rigors of frequent use without losing its effectiveness. I've been impressed by the variety of items I've been able to retrieve, from discarded metal debris to lost items such as keys and tools. Additionally, the magnet's design allows for easy attachment to ropes or cords, facilitating retrieval from deep or hard-to-reach areas. Overall, I'm extremely satisfied with my fishing magnet purchase, and I highly recommend it to fellow anglers and outdoor enthusiasts.

PROS -being able to effectively turn it on and off is really useful -very strong magnet -there are some threads on the case that I could conceivably use with clamps to hold non-ferrous items to a ferrous item CONS -the handle is _very_ difficult to move from the “off” to the “on” position, and vice versa. NOTES -I don’t _think_ it’s an electromagnet (no battery, no external electrical input), So I’m really curious as to how this works! It’s something mechanical, does maybe just moving a permanent magnet up away from the lower surface give enough distance to have a zero magnetic field at that surface? I would find that surprising, given the strength of the magnet. -I suggest to the manufacturer to make the handle a more comfortable, and secure, lifting surface. It’s a bit smooth, perhaps put some knurls in there for fingers to fit in to, and roughen the surface. MY STAR RATINGS: 1* substandard, mostly cons 2** barely acceptable, cons outweigh the pros 3*** meets the basic requirements, cons balance the pros 4**** good product, pros outweigh the cons 5***** exceptional, all (or almost all) pros

Der Magnetpro Mehrzweck-Schaltermagnet überzeugt vor allem durch seine enorme Haltekraft. Gerade wenn es darum geht, schwere metallische Gegenstände sicher zu fixieren oder zu heben, leistet dieser Magnet hervorragende Arbeit. Die ON/OFF-Funktion ist besonders praktisch: So kann der Magnet punktgenau eingesetzt und genauso einfach wieder gelöst werden. Das funktioniert überraschend gut! Ein weiteres Highlight ist die Vielseitigkeit: Nicht nur für Schweiß- und Hebearbeiten eignet sich der Magnet ideal, sondern – so wie bei mir – auch für den Alltag in der Werkstatt. Kleinere verlorene Metallschrauben oder Muttern lassen sich damit spielend leicht wiederfinden und aufsammeln. Die Verarbeitung ist solide und das Handling insgesamt sehr bequem. Fazit: Ein wirklich starker und zuverlässiger Magnet, der in keiner Werkstatt fehlen sollte. Für unterschiedlichste Anwendungen bestens geeignet und auch für das schnelle Aufsammeln von Kleinteilen ein echter Mehrwert! Absolute Kaufempfehlung.

Cet aimant ultra-puissant me permet de monter des dispositifs de mesure sur mon marbre en fonte avec la garantie que rien ne bougera, même avec un porte-à-faux très important. Afin de faciliter la mise en place du dispositif, il est possible de placer le commutateur ON/OFF en position intermédiaire pour obtenir une force d'adhésion médium. Des filetage M5 et M6 positionnés sur les différentes faces de l'aimant permettent de facilement y fixer les accessoires voulus. Attention, si l'aimant est tenu dans le vide ou positionné sur une surface en métal de faible épaisseur, il est très difficile voire impossible de faire tourner le commutateur et d'activer l'aimant. Contacté à ce propos, le fabricant m'a confirmé que c'était un comportement tout à fait normal de cet aimant et en aucun cas un défaut.

Qualité au top

so i dont use this in a metal shop, this will be your unconventional review haha. i have tested it on 1/2" steel plate though in our yard and itll lift a pretty decent sized plate, i dont know the exact size of it but if i had to guess maybe 5 sq ft. anywho, im a commercial diver in the mississippi river and we rely on magnets in high current to keep us on our work station if theres nothing to clip/tie onto. now the current of the river kicks pretty good some days, and i dont know exactly how much weight i put on this magnet at times but i can tell you that with it put on a rusted and scaled up piece of 5/8" steel (probably closer to 1/4" and all the way down to 1/8" in some spots) ive been able to hold my body weight (roughly 160lbs) in up to 10mph currents, on this magnet mounted sideways (visualize mounting it above or to the side of your body with all the weight pulling this magnet to the side, which it is strongest when pulled directly up)

Non l'ho ancora provato concretamente ma mi sembra molto potente e molto ben fatto, molto bello!
