How strong is the actual magnet?

Not very strong. I use them to hold laminated paper signs to my board, I use at least 6-8 for a laminated half a piece of paper.

I was disappointed to find that I couldn't use the magnet to pick up a paper clip I had pasted to a paper fish for a fishing game for my children. I definitely needed to double (if not triple up) for the fishing game to work.

Not very. It took three on the back of a small tin filled with dried herbs. If you have room to use more than one, it does the trick.

Not very. I purchased these to hold a dry erase board to the fridge. These were not strong enough to do the job (even using all of them to cover the back of the board).

It is not attracted to a magnet, so I would say it is either a very solid plastic or a non-ferrous metal.It is a very sturdy material. Hope this helps.

I'm afraid it depends on the strength of the magnet. A decent magnet should.

Yes. Super strong. Not too strong so one can't pull node off but you really have to commit to pulling them off. They really are good. My previous ones ( different brand) did not hold very good - these are heavy duty and heavy. The magnet is so good that it's tricky putting them on the wall as the metal place holds super tight that it was difficult to seperate for installation.

You'd have to be pretty strong. It is plastic with a little magnet on the end.

I have never had a problem with the magnet allowing the case to open when it should not.This is very subjective but I would rate the magnet at about an 8 only because a little more magnet strength would be nice.

The magnets are stronger than I expected. I have mine holding up a birthday card on the fridge and haven't had any issues with it falling or sliding off.

I'm not sure unless the weight was evenly distributed on the magnets. It's really not what it was built for. Maybe a 25 percent chance?

I think they would be very strong. I only have 1 of these magnets, and it is very powerful. If I stick it to a metal door jam or metal pipe, it is EXTREMELY difficult to remove. I have placed a metal file on top of a 3/4" thick c-top and with the magnet on the underside of the top it moves the file easily. I've also stuck it to my 24' tape measure hanging on my jean pocket and then stuck my 18 volt Hitachi cordless drill to "It". Just examples of how powerful this magnet is. I use it to find metal studs in the wall for installing cabinets in the commercial field, and absolutely love it. I don't know if this helps you but with the 2 magnets pulling toward each other on the 1" glass with the pad between, I think it would work.

For reference : Small bar magnet ~ 0.01 Tesla 100 Gauss Strong lab magnet 10 Tesla 100,000 Gauss I'm guessing this one is on the low end ...

They are pretty strong.I used mine to secure kitchen cabinet doors that didn't want to close properly. If one magnet per door doesn't work, then I'm sure multiples would.

The magnet is incredibly strong, it will surprise you. It won't have a problem sticking to the fridge as long as you don't have a stainless steel fridge in which case no magnets will stick to it.

These magnets are very STRONG! The adhesive is not flat on the magnet. There is a small amount of foam backing on the adhesive. If that doesn't interfere with your needs, then you may be confident that the magnets are strong enough for you.

the magnet tip is not strong enough to damage any electrical devices or cause EMI. it is only strong enough to hold a very small screw like those on an iphone.

I held mine up to a magnet it did nothing. I'm gonna say not magnetic. Hope that helps :)

Not sure of guage, but it seems quite sufficient. There is no magnet. Haven't had problem with any mice, but a raccoon has raided it a time or two. I suppose adding some weight to door would defeat mice.

The magnet is secure, but still breaks away with very little force. I have only used it in hiking situations and it breaks free with one finger. I think it would pop off as you push away.
