What are the properties of irregularly shaped magnets?
They are magnetic; irregularly shaped magnets have the property of attracting iron objects.
They possess magnetic poles; every irregularly shaped magnet has two magnetic poles, a North pole (N) and a South pole (S), which exist in pairs.
Temporary magnets and permanent magnets: When a ferromagnetic material is magnetized and easily loses its magnetism, it is called a temporary magnet (e.g., iron);
When a ferromagnetic material is magnetized and does not easily lose its magnetism, it is called a permanent magnet (e.g., steel).
When two irregularly shaped magnets are brought close together, like poles repel each other, and unlike poles attract each other.
Therefore: Like poles repel, and unlike poles attract.
