Hint:
We know a magnet has two poles: the north pole and the south pole and we know the magnetic field starts from the north pole and ends at the south pole. These poles always exist in pairs. With the help of magnetic strength, we are able to find out where the maximum iron powder exists.
Complete step by step solution:
We know in a magnet there are two poles. That is the north pole and the south pole and each pole has its own magnetic field strength.
Let us consider an iron object that is attracted by the magnet. When we take the object closer to the magnet, the object gets attracted towards the poles. In simple words, we say that where the magnetic field is more crowded there will be more strength and the iron object will be more attracted towards those points. We know the strength of the magnetic field is maximum at the poles (ends) of the magnet, as the magnetic field lines originate from the north pole and end on the South pole.
Hence, the ends of the magnet have the maximum magnetic field.
Thus, Option (D) is correct.
Therefore, the correct option is D.
Note:
It is to be noted that the strength of the magnetic field is maximum at the ends of the magnet and minimum at the center just outside the magnet. That is why maximum iron powder is collected at the ends of the magnet. So, recall all the properties of magnetic fields so that such types of questions can be easily solved
