How important is the magnet on the back of the hot-end?

I go through quite a few hot-ends on my A1 !!!

I am wondering how important is the magnet on the back of the hot-end?

I thought it was only there for the filament sensor? Some are strong and some are weak but does this make any difference?

Thanks for your input on this

As far as I know that magnet is solely for location and positioning, not for sensors.

The magnet is purely used to hold the hotend assembly in place until it’s clipped in. I promise the actual machined heat transfer zone on the hotend is where all the heat is being introduced, it wouldn’t be very useful to heat up the heatsink.

@Jalan at most, it may be needed for a “nozzle is installed” sensor, but it serves no purpose beyond that.

But let’s talk about your hotend consumption. Why are you going through them so fast?
