Do Speaker Magnets Alloy With Metal Or Aluminum ?

Question

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 an aluminum or metal 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 metal or aluminum ladder right next to those music keyboards will be a bad idea because I am putting aluminum or metal 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 ladder so close to those speaker magnets , whether or not any type of magnetism will alloy to my ladder or have any signs of magnetic responses after the ladder has been removed & away from those speaker magnets. I just don't want to put my ladder so close to those speaker magnet speakers of my keyboard & have magnetism of any levels still on my ladder when it is removed & away from my musical keyboards' speaker magnets. I am hoping no magnetism will be on my ladder once I am done using it & have taken it away from being right next to my musical keyboards & their speaker magnets. Thank you.

Update:

No offense

Update 2:

I also mentioned that the ladder may be made of "METAL" as well. I don't know which if it's aluminum or metal or if neither Metal nor Aluminum are effected by magnetic fields or magnet related items such as my music keyboard speakers. Sometimes I can't tell the difference between the aluminum ladders from the metal ones. Aluminum

Update 3:

By the way , I don't own a compass. I lost it when I was in the Bermuda Triangle last. Sorry. ;-)

Update 4:

Thanks everyone for your answers so far. I am just waiting for an answer in relation to if this ladder of mine is made from metal

Update 5:

Important Notice !!!

I just checked what the ladder is made of

You can't magnetize aluminum all by itself. It must be alloyed with nickel iron and cobalt.

Plus the magnets on the speaker are round magnets and are in very close proximity to the coil where the magnetic difference is what gives the speaker it's movement. Anything sitting even an inch or two away will not detract from the speakers

Any aluminum made object has no affect by magnetic field. Aluminum blocks magnetic field. It is a non magnetic metal. Besides, magnetic field comes from small speaker just has an effective range a few inches away from its main magnet. Test it with a compass to see its effect.

The ladder will not be harmed by magnetism, no matter what kind of magnets you put on it, no matter what kind of magnetic object you put next to the ladder.

If any part of the ladder becomes magnetized, the magnetic field will be puny and no threat to any person or object.
