There was/is a long-held fear in Nordic countries that increased international migration would bring people merely/primarily interested in becoming parasites on the body of society. Never intending to integrate or become productive members of society, but to settle for a life on social support.
And it probably happens, occasionally.
However, the overwhelming majority of migrants/refugees try very hard to become productive members of society, to carry their own weight.
In all the welfare magnet theory has NOT proven correct.
No country invented the magnet. Magnets are naturally occurring objects. The Chinese were the first to use a magnet as an aid to navigation.
Probably because our welfare system is a magnet for every other country in Europe - and we (apparently) don't really seem to be able to refuse anyone 'claiming asylum !

The hypothesis for separating iron filing and sulfur powder using a magnet is that iron is a magnetic material, whereas sulfur is not. By using a magnet, we can separate the iron filings from the sulfur powder based on their magnetic properties.

Hans Christian Oersted's hypothesis was that an electric current produces a magnetic field around it. This hypothesis led to the discovery of electromagnetism and laid the foundation for the development of the field of electromagnetism.

Magnet. Oersted's hypothesis was proven correct when he observed that a compass needle placed near a wire carrying an electric current would deflect, indicating the presence of a magnetic field around the wire.
An hypothesis is an idea, notion, conjecture, assertion or statement about reality. The activity we call science is about putting forward and testing hypotheses. For example, you could test your notion that nickel might be magnetic by putting it near a magnet. If it was clearly attracted, you could suggest that "nickel is magnetic" was not just an hypothesis but a fact. If not, you might test with an even stronger magnet, and so on. Testable hypotheses, especially those that help to explain why things act the way they do, are important because they prompt activities which can improve scientific knowledge.
If a magnet does not stick to an object that is supposed to be gold, then it is likely not pure gold. Pure gold is not magnetic, so if a magnet is attracted to the object, it may contain other metals or be a gold-plated material. You should consult with a professional to confirm the authenticity of the item.
