Pallas BB Magnet Question

Hi all! I am a newbie and just bought a pre-loved Pallas BB about bag today! I’m in love! My question is- does anyone know if the magnetic pockets on both sides of the bag could damage my iPhone X or credit cards?? I want to store my phone in one of the exterior pockets. It may be a silly question but I am nervous as I have been told to keep electronics away from magnets in the past.
