My layout consists of Bachmann EZ track, I have the Bachmann magnetic knuckle couplers but do not know how to use them with a magnet. I looked it up on YouTube but there is nothing that shows how to do it for the EZ track. I know you have to buy a magnet? Where do you put the magnet? But I don't know what? Please help and thank you.
You don't say what scale you're using.
If HO you can use the 'Magnet w/Brakeman' #78999 http://shop.bachmanntrains.com/index.php?main_page=product_info&cPath=258_273&products_id=4836 (http://shop.bachmanntrains.com/index.php?main_page=product_info&cPath=258_273&products_id=4836)
Or, if you want to see the magnet location without brakemen all over the place, you can use one of the Kadee between the rails magnets. Even though EZ-Track is Code 100 rail, the Kadee Code 83 magnet will work, and is less likely to snag anything.
If you're N scale then you want the 'Magnet w/Brakeman' #78998 http://shop.bachmanntrains.com/index.php?main_page=product_info&cPath=879_604_786_787&products_id=2764 (http://shop.bachmanntrains.com/index.php?main_page=product_info&cPath=879_604_786_787&products_id=2764)
Or you can use a Micro-Trains magnet if you prefer between the rails.
Kadee has an explanation of how they work here https://kadee.com/animation/c1.htm (https://kadee.com/animation/c1.htm)

The Bachmann magnets have sticky stuff on them so you can stick them to the underside of the EZ Track. Then, put the brakeman alongside the track where you have the magnet underneath.

Tiebreaker's shows you how to use it with the magnet in place.
This video (part 1) shows attaching the magnet under the track at about 2:10 spot in the video
