Question

Does magnetic field inside a solenoid same at all points

Answer 1

Solenoid

Solenoid is such megnetic device in which then wire through which current  has to flow have several turns.

Does magnetic field lines inside Solenoid same at all point?

Answer : Yes because several turns in the coil results parallel lines  of  magentic  field  inside coil/solenoid.

These parallel magnetic  field  lines represents that magneic  field  inside a solenoid is same at all points

Note : In the attatchment, grey colour lines is for coil/wire through which current  flows.

While the blue lines are the magnetic  lines  around current produced.

Answer 2

Yes, the magnetic field inside the solenoid is same at every point as all the magnetic lines are passing parallal to each other inside the solenoid.

But it is different for all points outside the solenoid except those which are on same magnetic line.
