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

An electromagnet with coiling of 100 turns because the more is coil the magnetic field will produce and hence it will become stronger than electromagnet with coiling if 50 turns.
