لَقَدْ اَرْسَلْنَا رُسُلَنَا بِالْبَيِّنٰتِ وَاَنْزَلْنَا مَعَهُمُ الْكِتٰبَ وَالْمِيْزَانَ لِيَقُوْمَ النَّاسُ بِالْقِسْطِۚ وَاَنْزَلْنَا الْحَدِيْدَ فِيْهِ بَأْسٌ شَدِيْدٌ وَّمَنَافِعُ لِلنَّاسِ وَلِيَعْلَمَ اللّٰهُ مَنْ يَّنْصُرُهٗ وَرُسُلَهٗ بِالْغَيْبِۗ اِنَّ اللّٰهَ قَوِيٌّ عَزِيْزٌࣖ  Indeed, We have indeed sent Our messengers with clear proofs and We have sent down with them the book and the scales (of justice) so that people can act justly. We sent down iron which has great strength and various benefits for humans so that Allah knows who helps His (religion) and His messengers even though (Allah) cannot see it. Indeed, Allah is All-Powerful, All-Mighty (QS. Al Hadid : 25)

Is a magnet the same as a magnetic material? Explain your answer

Magnets and magnetic material are different

Magnets can attract and repel one another. Some materials such as iron and steel are magnetic. Magnets attract magnetic material.
Some material such as plastic and paper are non-magnetic and they are cannot attracted by magnets

What are the differences between magnets and magnetic material?

​Which parts of the magnet are most of the iron fillings attracted to?

• You have learnt that unlike poles of magnets attract and like poles of magnets repel each other.

• The force that attracts or repels another magnet or attract magnetic material is called magnetic force.

• We cannot see magnetic force, but we can see its effect on magnetic material or other magnet.

• Magnetic force is strongest at the poles of a magent.
