Answer 1

Get it from you old speakers the bigger the better

Answer 2

You don't need to buy one.  It is not a bar magnet but a round donut magnet.  Just find an old Microwave and they have two very good magnets in them.  Also you can find a powerful magnet in an old computer hard drive, the older ones have the best ones in them.
