i need help for my assignment.

On a steel wall, the micro switch is used to activate and deactivate the electromagnet. Electromagnet will be energized just before it touches the steel wall and de-energized jus before losing contact with the wall in both directions. Write truth table and design the logic circuit to control the electromagnet.

pls see the attachment for the picture. thanks alot

a logic cct is not required.
you are simply using a switch to make and break a magnet (on one wall?).
*** magnet energizes- moves to wall- switch opens- magnet de energizes and swings away from wall- switch closes- magnet energizes-.......
