The magnet creates a magnetic field which is focused by the pickup’s pole piece or pieces. The permanent magnet in the pickup magnetizes the guitar string above it. This causes the string to generate a magnetic field which is in alignment with that of the permanent magnet.

How often does the pickup ability work?

If more than one Pokémon has Pickup or Harvest, the faster Pokémon will restore an item first. If multiple items can be collected, the Pokémon will collect the item most recently consumed. A single Pokémon’s Pickup will not activate more than once per turn.

Does pickup work if you run?

Pick Up only works after a battle. Running away from a battle isn’t the same as finishing a battle.
