Describe magnetic field due to solenoid. (In short)
  • 1 answers

Gaurav Seth 5 years, 5 months ago

  • A coil with many circular close turns of insulated copper wire (like a cylinder as shown above) is a solenoid.
  • One end of such a solenoid behaves like the north pole and the other as a south pole.
  • Therefore magnetic field due to current in the solenoid is similar to a bar magnet. The fields always emerge out of the North pole and always merge into the South pole
  • The field inside the solenoid is uniform.
  • The strong magnetic field inside the solenoid is so strong that it can be used to magnetize a piece of soft iron when it is placed inside the coil. The magnet formed like this is called a Electromagnet
