Question: Does this magnet carry a power switch similar to a Electromagnet? I need one that powers on.
Document: What can I say other than love it. The rubberized handle is great and the magnet has great power!
This unit comes nicely packaged... the bottom of the magnet is actually two separate magnets side by side. They work as advertised, and having a handle to grip them was well worth it. I used it for separating black sands while prospecting... the shape was excellent for this, as i could wrap a plastic baggie around the bottom (to keep the magnet clean) and still have access to the handle - it was a pleasure to use. Beyond prospecting, I could see many uses for this magnet and i would buy another one like this for sure, especially at the price!
The magnets in this unit work just as I expected. They can be used either in the handle or remove just one at a time. I like the covers for the magnets so it won't stick to something you aren't expecting.
This is no cheapo magnet. I can pick up a full ammo can with just the magnet. And the price is good too.
I placed the magnet on the door and it easily pulled the door open. I keep finding new tasks for this handy tool.
When I'm trying to keep heavy boards or sheet stock aligned, I grab the metal handled Magnet Sources first, and then supplement with these as needed.
We bought a piece of property that had a bunch of loose nails and screws on it. I was hoping I would be able to quickly and easily pick them all up with this magnet, but I wasn't. You have to be right over the item for it to work. (about 3 inches max)
A good magnet but about 1/10 of the lift capacity claimed. I was able to pull straight back to separate this from a steel plate. (no I did not twist it and yes I took the protective caps off)
To call this handle magnet powerful is hyperbole as other reviewers have pointed out. I doubt that it will lift more than 15 lbs. It should work for me in holding PVC roofing in place on steel beams until I can clamp them. The thin PVC sheets only weigh a few pounds each so we will see.
The description on Amazon says this magnetic handle has 100 lbs of pull. However, when the package is received it will say 'holds 100 times it's weight'. I tested it against about a 25 lbs metal box, and the magnet would not hold the box.This is a unacceptable deception.
Answer: yes
