|Magnet's in-game sprite from Mega Man 3|
The red side of the Magnet has a powerful magnetic field what will pull the player towards the Magnet if they enter it, while the silver side does not. The player character is not affected by Magnets while holding onto a ladder. The Magnets only affect the player character.
The magnetic field created by the red side of the Magnet has and area of 2 tiles high vertically, and 5 tiles wide horizontally (refer to yellow area in the example diagram below).
When the magnetic fields of two Magnets overlap, the overlapped area will cause both magnetic fields to cancel each other out (refer to the purple area in the example diagram below).
The Magnet can potentially be dangerous due to possibly pulling the player into enemies or hazards, or off of small blocks and platforms.
The Magnet can potentially be helpful due to possibly allowing the player to travel farther over pits by pulling the player closer to the other side.
