magnets lose strength
What will hapen if you freeze a magnet?
Will it loose all it’s magnetism? Or lose it’s strength? Or stay the same?

I’m not quite sure what you mean by freeze. If you mean take it to the freezing point of water (0C or 32F), then nothing will happen. It will just be cold. In fact, for a regular magnet, nothing should happen as you cool it to any temperature. If you got it really really cold, you might even see its magnetism go up.
But if you heat a magnet up, it will lose its magnetism at a certain temperature. A magnet is magnetic because each of the atoms in the magnet are magnetic and they all line up in the same direction. When a magnet gets too hot, the atoms inside it will be jiggling around so much that they start to not point in the same direction, so the overall magnetism goes down. If you heat it up so that happens, and then cool it back down, eventually, it will get cold enough that the atoms line up again, and it would get its magnetism back. This is what I would call freezing a magnet, but it would be pretty hot compared to frozen water. And if you did this, the magnet would not be as magnetic as it once was because not all the atoms will line up in the correct direction. To get it back to full magnetic strength, you would need to put it in a string magnetic field to make all the atoms line up with the field and each other.
