Do Speaker Magnets Alloy With Steel ?

I have a couple of musical keyboards in my bedroom closet. The keyboards have 2 speakers in them on each side that have speaker magnets on the back of the speakers inside & are part of the music keyboard. I am wanting to bring in a Steel ladder into my bedroom closet & set it right there in front of or right next to a few inches from those keyboards to put something high up on a shelf in that closet. I am wondering if my putting that Steel ladder right next to those music keyboards will be a bad idea because I am putting Steel ladder right next to music keyboard speakers that have magnet based speakers that can somehow have a natural magnetic response in bringing those 2 items closer together like a magnet sticks on a refrigerator. I am wondering that after I use that Steel ladder so close to those speaker magnets , whether or not any type of magnetism will alloy to my Steel ladder or have any signs of magnetic responses after the Steel ladder has been removed & away from those speaker magnets. I just don't want to put my Steel ladder so close to those speaker magnet speakers of my keyboard & have magnetism of any levels still on my Steel ladder when it is removed & away from my musical keyboards' speaker magnets. I am hoping no magnetism will be on my Steel ladder once I am done using it & have taken it away from being right next to my musical keyboards & their speaker magnets. Sorry for repeating myself so much in my sentences. I am well aware of it & I am sorry. Terrible habit. My bad. Thank you.
