Out in deep open space would the ambient/background energy be lower than here on earth?

If a simple bar magnets' fields spacings/field of reach were 'x' distance here on earth, would the distance 'x' of these field spacings/fields of reach increase because of a lower ambient/background energy out in deep open space?

To what ambient/background energy are you referring?

Yes.

If you are thinking about energy coming from stars, obviously it follows inverse square law.

And the largest energy will be coming from the nearest star, the nearest galaxy.

On the Earth we have [latex]1367\frac{J}{s*m^2}[/latex]

100 a.u from us, it'll be [latex]0.1367\frac{J}{s*m^2}[/latex]

(2.5 further than Pluto, somewhere close to aphelion of Eris)

Thanks Sensei/swansont for Your reply, having confirmed ambient energy levels are less in deep open space I'll try reword what Iam trying to find out.

If then say a small permanent magnets' field of reach was say 1cm to initiate a pull on 1g of iron to its' body on earth, would this range of 1cm to initiate this pull on 1g of iron increase in deep open space due to lower background energy levels or would this reach of attraction be the same in both locations earth/deep inter-galactic space.

The strength of a magnet does not change with its location or external energy levels (unless that energy heats it above its Curie point).

That is not a very precise definition; you would need to quantify what the size of that pull force is (in dynes, presumably, as you are using grams and centimetres).

I think he is asking if it would increase, or not. It is not necessary to quantify it for that purpose.

True. It was just an afterthought, to suggest how the definition could be improved (if necessary).

Thanks Strange and JC for Your replies.
