Electromagnet precautions!
The electromagnet in use meets the following conditions to achieve the maximum suction value
1. The effective adsorption distance is 0mm (must be veneer adsorption) can not be separated from any object
2. The surface of the object to be sucked should be very smooth and clean
3. The suction contact area of the object to be sucked must be greater than or equal to the suction surface of the electric sucker (that is, the maximum outer diameter of the electric sucker).
4. The suction of the sucked object can reach the nominal value only if the thickness is greater than 8mm, and the suction decreases as the thickness decreases
5. Correct use of power supply and rated voltage
6. The object to be sucked must be a material with good magnetic conductivity such as (electrical pure iron, low carbon steel, silicon steel sheet, etc.)
7. Try to avoid vacuuming (vacuuming hot) during product work, and normal adsorption heating is a normal phenomenon

Mine doesn't work, just like 100g force (I got the 20kg one). It's drawing ~0.2A@24V Anyone figure out how to make them work? Or just lots of duds?

The electromagnet has many industrial uses. As long as it's energized, it will tenaciously hold something open or closed as needed. Turn the power off, and it's has no magnetic field. I got this for a DIY use. I connect it to a 24 volt DC transformer to energize it. I then drag screwdrivers in one direction across it to magnetize them. It will make an unmagnetic screwdriver magnetic. It will revitalize a screwdriver that has lost its magnetism. This is what I use it for. Disclosure: I can't recommend you use it for that unless you consider all safety concerns.

my husband uses magnets shaped like this to search for metals & other dorky things.this piqued his interest into possibly another sort of activity off the basis of his usual activity.the magnet in this is incredibly strong.one you wire it correctly, the inclusion of the electrical aspects are accurate & respond immediately.without electrical wired to this - it will not work.

This is a review of the 24V, 70x10mm magnet with nominal 20kg suction. This magnet will work in “some” capacity at lower voltages, and I tested it all the way down to about 3V before I lost all noticeable magnetism. I think this does have a 20kg suction, under “ideal” conditions. You need to think about how much field is interacting with how much material – the more interaction, the more suction. I tested, subjectively, with 3 conditions:Test condition 1: I put a screwdriver tip to the magnet. It was clearly sticking, but was very easy to pull the screwdriver away. Not a lot of material in that screwdriver tip for the magnetic field to interact with.Test condition 2: I put a bulky pair of pliers on the magnet. It held very firmly, but I could still remove the pliers with some mild effort. Bulkier pliers = more material for the field to interact with = more suction force.Test condition 3: I put the magnet flat on a 1/8 inch thick slab of steel. I could not remove it by hand, no matter how hard I tried. I tried to pry it off with pliers, and also was not successful. Lots of material everywhere (and thickness matters, not just surface area) for the field to interact with = lots of suction power.At 24V, this pulled about 267mA, putting the power around 6.5 watts. I think this has amazing suction for such low power consumption. I’m not able to measure exact kg of force, but I know that it holds very, very firmly when it’s a full slab of steel. This is exactly what I wanted, and exactly what I expected (just physics of magnetism), so I’m giving this 5 stars.

I like the idea of a electro magnet for a automation project I am working on, but this thing just doesn't have enough pull for me. Maybe just a bad application on my part, not the makers fault.

This magnet weighs about 1/2 lbs and draws 0.12 Amps at 12 Volts DC. I attached it under a steel strap and it was able to support it's own weight until I reduced the voltage to 2.0 Volt before it let go of the strap. It is made well and the metal has a bright shine to it.
