Answer 1

Magnetic cards are are ancient ancestors of smart cards. Since they have no intelligence whatsoever - imagine them as a plastic card with a glued-on magnetic stripe - the magnetic card reader/writer is the instance understanding commands. Note that there are readers without possibility to write at all. (Swipe-through readers don't have the precision needed for reliable writing, you need a motor for that).

Look at the manual of the magnetic reader/writer, there was little standarization and most likely, the reader is attached to a computer using a serial RS-232 interface. While there are reserved data object IDs on smart cards inventend to store track1..track3 for an migration period, even those are now outdated since ages.

Answer 2

Magnetic Strip cards do not communicate with APDU commands, only an ISO-7816 smart card uses APDU commands. A magnetic stripe card is like a cassette tape, there is only data recorded or written to that media and follows the ISO-7810 specification on how that is done.
