Beautiful but ... magnets almost useless toys!

The aluminum door on which I want to put the net is equipped with rails for a mechanical shutter. I use very rarely, if ever this component and so I decided to install the curtain into the guides.
I cut a wooden stick to attach the top of the screen to drag the top of the door. I hold the stick with two small screws attached in the slides.
To fix the outer sides of the curtain in the slide, I simply used pieces of thick rubber hose I slip, squeezing, in the slides of trapping the edge of the curtain panel.
And it holds very well and in addition, if a child rushes through the curtain, it can come off easily without tearing. That's live!
D This system is highly resistant to wind.

Unfortunately, magnets, they are not up to the task! At the slightest breath of wind, the curtain opens :-(
But I found an inexpensive solution: I bought small magnets neodymium N42 3 * 12 mm and I placed one of these magnets on each of the original magnet holder of a curtain. It works fine now and the curtain resists even relatively violent wind. It is not even necessary to place these little (tiny) magnets on the other side of the curtain. I tried that but then the opening of the curtain becomes difficult and there is then a risk of tearing.
