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

A uniform magnetic field has the same strength and direction at all points in space. In contrast, a non-uniform magnetic field is one where the strength and/or direction varies from point to point. Uniform magnetic fields are often created in laboratory settings, while non-uniform magnetic fields can occur naturally or in more complex magnetic systems.
A uniform magnetic field has constant strength and direction throughout the region. A non-uniform magnetic field varies in strength or direction in different parts of the region. Uniform magnetic fields are simpler to work with mathematically, while non-uniform magnetic fields can lead to more complex behaviors in magnetic materials.
A uniform magnetic field has the same strength and direction at all points in the space, while a non-uniform magnetic field varies in strength and/or direction. The strength of a magnetic field can be calculated using the formula B = μ0 * I / (2 * π * r), where B is the magnetic field strength, μ0 is the permeability of free space, I is the current, and r is the distance from the current.
Magnetic force is a non-contact force.
Magnetic materials are materials that can be magnetized and can create a magnetic field, such as iron and nickel. Non-magnetic materials do not respond to magnetic fields and cannot be magnetized, such as wood and plastic.
Magnetic fields can pass through most materials, including air, vacuum, and non-magnetic substances like wood or plastic. However, magnetic fields are affected by ferromagnetic materials like iron, nickel, and cobalt, which can alter their behavior or be attracted to them.
