A fridge magnet, or any magnet for that matter, was initially designed for decoration or to hold simple reminders (grocery notes) onto a metal fridge door. This was designed back in the day for women (vaginas), since they stereotypically tended to matters relating to the kitchen. Also, a fridge magnet is a material object, fabricated and developed to make money for people. These people include men. Men make business to make money. Men make this money to attract women (aka vagina).
