Hi,

The magnet may actually be a magnetized inductor.

Has it got a dot marked on the casing at all, on one side or offset on the top?

(A bit like an electrolytic capacitor - you have to know the +ve and -ve end)

If so is there a similar dot or + sign on the board where the component belongs?

Post a picture of the component and the board which may help others to help you.

Here's how to do this

在已经存在的问题里加入图片

You could always check on Ebay etc to see if there is exactly the same board for sale (the one where you think that the component belongs) which have images of the board which hopefully can be enlarged to show the component in question to see which way it is connected. Just a thought.
