If it's possible, an electronic circuit with magnetic switches

Hi,

I'm looking for some help to see if a circuit is possible and how I would go about figuring what parts / power I would need ?

I'm looking to design a circuit which features 7 LEDs ( ranging from 2.2v to 3.4v) the main element I'm wanting to include is to have each LED activate as soon as a magnet is introduced & them turn off as soon as its removed without effecting the other LEDs.

I have seen circuits with 1 LED powered this way using 2x 2032 batteries but what just wondering if there was a simpler way rather than having 7 separate circuits with 7 separate power supplies.

Apologies for the lack of knowledge but just wanting to see if its possible.
