An electromagnet can be made by using a wire and coiling it around an iron core that is very hard.
After the process of coiling, current can be passed through it.
This is the usual procedure that is followed in schools to make an electromagnet.
Apart from that, people can also make an electromagnet manually and they need to do constant friction between an iron bar and small magnet.
After constant frictions, the iron bar will turn into a temporary electromagnet.
