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.
When a object travelled equal distance cover with equal internal of time
Uniform magnetic field depends on the position of its surrounding. A non uniform magnetic field changes its position from one place to another.
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
straight parallel lines
A magnetic domain refers to a region within a magnetic material that has uniform magnetization. Two materials with a weak magnetic domain are bismuth and pyrolytic carbon.
emf is only induced if the flux through the loop varies with time. if u keep it in a nonuniform magnetic field, the flux wont be uniform throughout the area of the loop, but whatever it will be , it will remain the same.. as at a point in the field, the field strength is same. means the magnetic field is not same at all points but if u consider a single point, there, it remains the same, its not changing. hence no emf is induced. hope u got it.
in uniform motion velocity not changes with time but in non uniform motion velocity changes with time.
a rough surface. uniform = same, so a nonuniform surface would be uneven and not the same. probably most rocks and surfaces that change or are not consistent.
That rather depends on the type of foil and the tolerances to which it is made. If you mean commercial cooking foil it is usually very uniform.
A nonuniform mixture means no matter how close you look at the mixture, you can't see the different ingredients. Take H2O for example, you cannot see the Hydrogen in the air.

yes, there is a NET field .electric dipole experiences a net field .(not in uniform E.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.

It is where the magnetic field have the same magnitude and direction in a specific region. Hope that helps
