Observations:

1. You will observe that the field lines inside the solenoid are in the form of parallel straight
lines.

2. When the current is reduced to 0, magnetic field intensity around the solenoid reduces to 0.

3. When we increase the amplitude of 'current' or the 'coil turn density', the magnetic field
intensity around the solenoid increases.

4. When we reverse the direction of current the polarity of the solenoid is also reversed.
