Question

17. What is a solenoid?
18. Draw comparison of magnetic field pattern due to current carrying solenoid and that
of a bar magnet.
19. The field lines inside the solenoid are in the form of parallel straight lines. What does
this indicate?
20. What is an electromagnet?​

Answer 1

Answer:

(17)A solenoid is an electromagnet which has a coil of insulated wire wound on a rod-shaped form made of solid iron, solid steel, or powdered iron which produces magnetic field when electric current passed through it.

(19)This indicates that the magnetic field is the same at all points inside the solenoid. That is, the field is uniform inside the solenoid.

(20) A soft metal core made into a magnet by the passage of electric current through a coil surrounding it.

(18)Magnetic fields of a solenoid and a bar magnet are similar.
