Question

Why is the magnetic field maximum inside the solenoid ?

( Explanation should be in the range of 50-70 words ! )

( Non-sense answers will be deleted on the spot ! )

Answer 1

The magnetic field lines travel along the length of a solenoid, and if you bend the ends around, you can get the magnetic field lines to go in a circle inside a torus- shaped coil of wire. You can increase the strength of the field by putting a magnetizable material inside -- a doughnut-shaped piece of iron, ....

it depends on the material and the turns of wire around it soft iron core is eligible to produced stronger magnetic field if we increase the turns of wire the magnetic field produced will be stronger
