No, just close.
A solenoid provides a magnetic field that is approximately uniform near its center. (One should compare this to a Helmholtz coil.)
The keyword is "approximate" and one really understand the assertion of uniformity to mean nearly uniform near the center. To say that it is a good approximation would mean that small deviations from the center produce variations that are small. Specifically, one would expect variations that deviate from a constant magnetic field to be no worse than quadratic with distance and that is actually correct. (It may even be fourth order but that requires a calculation to check.)
To give another rough idea of the field variation, it is simple to prove that for a long solenoid, the field at the end is half of the field at the center, so it does vary by a factor of two along its length.

What is a uniform magnetic field?
It is where the magnetic field have the same magnitude and direction in a specific region. Hope that helps
What is domain in magnet?
A magnetic domain is a region of uniform magnetization within a material.
Definition of uniform-magnetic field?
they are parallel to each other and maintain equal distances............
What type of magnetic poles do the domains at the north poles of a magnet have?
This is a really confusing question, but I believe you want to know how the magnetic domain at the north pole of a magnet is. The answer is uniform.
Why magnetism at the centre of a bar magnet is zero?
F = mB - mB =0 a bar magnet is placed in a uniform magnetic field B, its poles +m and -m experience force mB and mB along and opposite to the direction of magnetic field B.
For a loop of current carrying wire in a uniform magnetic field the potential energy is a minimum if the magnetic dipole moment of the loop is?
in the same direction as the field
Can a solenoid suspended by a string be used as a compass?
A solenoid can be used as a compass when a DC current is going through it because when a current is going through the solenoid, the magnetic field lines are nearly uniform and perfectly parallel inside of it, giving it essentially a north pole and south pole.
How does a solenoid act as a magnet?
When current is passed through a solenoid coil, magnetic field produced due to each turn of solenoid coil is in the same direction. As a result the resultant magnetic field is very strong and uniform. The field lines inside the solenoid are in the form of parallel straight lines along the axis of solenoid. Thus, the solenoid behaves like a bar magnet.
Uniform And Non-Uniform Magnetic field And Calculation of its strength?
The answer depends on the source of the magnetic field. For instance, the magnetic field due to a current carrying wire is given by the formula mu*I/(2*pi*r). Magnetic fields follow the principle super position so they can be added up no problem.
How do you produce a uniform magnetic field?
To make a long story short I wanna mention the name of several methods to make uniform dc magnetic fields: Using the space inside a solenoid Using the Helmholtz coil Using the Maxwell coil as all of these configurations take benefits of the phenomena in which current produces a magnetic field, the amplitude of the magnetic field would be easily controlled by control upon the current passes the loops of windings.
Is it possible to orient a current loop in a uniform magnetic field such that the loop will not tend to rotate?

What is uniform and non uniform magnetic field?
Uniform magnetic field depends on the position of its surrounding. A non uniform magnetic field changes its position from one place to another.
What do you mean by uniform and non uniform magnetic fields?
In a uniform magnetic field the imaginary magnetic lines of force are parallel to each other. But in case of non uniform they are not parallel
How it can be possible to produce electric current in a uniform magnetic field?
-- Form a continuous circuit out of a conducting material. -- Move the conductor through the magnetic field, at an angle to the magnetic 'lines of force'.
How uniform is magnetic field in current loop?
A current loop, by itself, does not produce a very uniform magnetic field. People use a Maxwell coil, Helmholtz coil, or a long solenoid, when they want a relatively uniform magnetic field. What is the magnetic field in a current loop? There are two magnetic fields in a current loop. There is the magnetic field caused by the current, such as what is found in a straight wire, and is given by B=ui/2pr where B is the magnetic field; u is the permeability constant; i is the current; p is pi; r is the radial distance from the wire. If the wire is now circular and has a radius R, then one can calculate the magnetic field inside the wire loop. Granted this is complex, but this is the idea. The second field is perhaps a little bit more practical, but really never discussed. One can solve this problem by assuming a vector A, the current density, then take the curl of vector A, and this is the magnetic field inside the current loop. The question is what is the vector A? The current density vector inside the loop is the product ir/R and a unit vector function representing a circle. This current density is only valid for r less than or equal to R. Here the r is measured from the center of the circle. For r greater than or equal to r, the current density is the product iR/r and the unit vector function representing a circle. This is complicated by the selection of the coordinate system representing the circle. My preferance is to use spherical coordinates, but most books use Cartesian coordinates, and as such the expressions are complicated i.e., r in spherical coordinates is r but in Cartesian coordinates is (x^2+y^2+z^2)^1/2. I hope this gives some insight to the question. I do have a solution in spherical coordinates, but cannot furnish it because of my inability to use greek letters.
What if a magnetic needle is kept in a non uniform magnetic field?
A magnetic needle kept in uniform magnetic field will experience zero net force but non-zero net torque........Since the magnetic lines are uniform,the force acting on each end of the needlewill be equal and opposite.So it will cancel each other resulting zero net force.
What type of magnetic field lines represent uniform magnetic field?
straight parallel lines
