Question

f) A current carrying coil of an insulated wire wrapped around a piece of soft iron becomes i. a filament, ii. an electromagnet. iii. a fuse. iv. a conductor.​

Answer 1

ii) an electromagnet

ExPlanation:

When current is passed through a insulated wire wrapped around a piece of soft iron then it becomes strongly magnetisd and this process of producing strong magnetic field by magnetising a piece of magnetic material like soft iron results in formation of a electromagnet.
