Correct Answer - Option 1 : Electromagnet

The correct answer is ​Electromagnet.

  • Electromagnets are made out of a coil of wire (wire curled in series).
  • This is more effective in producing a magnetic field than just a wire running straight.
  • This effect can be strengthened by winding a wire tightly around a powerful core, made of magnetic material, such as iron.
  • Electromagnets are also used for industrial applications, such as magnetic lifters that use magnetic attraction to lift heavy objects or magnetic separators that are responsible for sorting ferromagnetic metals from scrap metal.
