about solenoid with some some explanation for exam
Answers
Solenoid is a current carrying coil of wire acting as a magnet.
The field lines inside the solenoid are in the form of parallel straight lines.This indicates that the magnetic field is the same at all points inside the solenoid that is the field is uniform inside the solenoid.
A strong magnetic field produced inside solenoid can be used to magnetize a piece of magnetic material like soft iron when placed inside the coil.The magnet so formed is called an electromagnet

A coil made by winding a conducting wire having large no. of closed turns is known as SOLENOID. It consists of a coil of a no. of turns of insulated copper wire closely wound in the shape of a cylinder. Inside a solenoid magnetic lines of force are just like parallel straight lines. Magnetic field is same at all points inside the solenoid.Magnetic field around a current carrying solenoid is shown in the fig above
