Write the pattern of magnetic field lines due to a solenoid |
|
Answer» Same as that of bar magnet A solenoid is a generic term for a coil of wire used as an electromagnet. It also refers to any device that converts electrical energy to mechanical energy using a solenoid. The device creates a magnetic field from electric current and uses the magnetic field to create linear motion. \xa0 1. The magnetic field for the current carrying solenoid \xa0 2 For bar magnet. \xa0 1. The poles of the bar magnet do not lie exactly at the end of the magnet but are somewhat inside. In a solenoid, poles can be considered to be lying at the edge. \xa0 2) The magnetism retains in the bar magnet naturally but in the solenoid, the magnetism is there so long current flows through it. \xa0 3) A magnetic field of a bar magnet emanates from throughout the body of the magnet, with more intensity at the poles. While there is no field emanating from the lateral surface of the solenoid. \xa0 |
