A solenoid is a cylindrical coil of wire whose diameter is small compared to its length.An electromagnet is a solenoid wound around a central iron core. The magnetic field generated by the coil of wire magnetizes the core, increasing the total magnetic field.

Answer:-

Solenoid:-

  • They are temporarily magnetized.  
  • A solenoid can produce very strong magnetic force.  The polarity of a solenoid can be reversed by changing the direction of current in its coil.
  • It can easily be demagnetized by switching off the current.  
  • It produces a magnetic field as long as there is current flow.
  • They are usually made from soft iron/steel.  
  • The strength of solenoid depends upon the quantity of flow of current.

Bar Magnet:-

  • They are permanently magnetized.  
  • A bar magnet produces a comparatively weak force of attraction. The polarity of a bar magnet is fixed and cannot be reversed.  
  • It cannot be easily be demagnetized.  
  • It produces a permanent magnetic field.  
  • They are usually made from hard iron/steel.  
  • The strength of bar magnets depends upon the nature of the material used in its creation.
