Boojho made an electromagnet by winding 50 turns of wire over an iron screw. Paheli also made an electromagnet by winding 100 turns over a similar iron screw. Which electromagnet will attract more pins? Give reason.

As Paheli's electromagnet has more number of turns of wire than that of Boojho's electromagnet. So, Paheli's electromagnet is much stronger than that of Boojho's. So, Paheli's electromagnet will attract more pins.
