It is represented by convergent or divergent lines. So, Uniform magnetic field lines are starlight lines whereas non-uniform magnetic field lines are curved. Uniform magnetic field lines will be parallel to each other; non-uniform magnetic field lines are not parallel.
What is uniform magnetic field?
Uniform magnetic field
When magnetic field lines are the same distance apart from each other, we say that the magnetic field is uniform.
What is the difference between uniform and non uniform magnetic field?
Uniform magnetic field lines will be parallel to each other, non uniform magnetic field lines are not parallel. Number of field lines per unit area does not changes with position for uniform magnetic field, but the no of field line per unit area is position dependent for non uniform field line.
How do you make a uniform magnetic field?
Creating a Uniform Field
- A uniform magnetic field is one that has the same strength and direction at all points.
- A uniform magnetic field can be created by taking the opposite poles of two magnets and holding them close together.
Where do we find a uniform magnetic field?
When magnetic field lines are parallel then magnetic force experienced by an object is same at all points in that field and such a field is called uniform magnetic field. For example a bar magnet’s strength is greater at its poles[non uniform] however inside a solenoid the magnetic field lines are parallel.
What is the purpose of a magnetic field?
Magnetic fields force moving electrically charged particles in a circular or helical path. This force—exerted on electric currents in wires in a magnetic field—underlies the operation of electric motors. (For more information about magnetic fields, see magnetism. The use of magnetic fields to generate electric current.
What is called magnetic field?
A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. … The effects of magnetic fields are commonly seen in permanent magnets, which pull on ferromagnetic materials such as iron, and attract or repel other magnets.
What do you mean by non uniform magnetic field?
Non uniform magnet :- The magnetic field in a region is non uniform if it has different magnetic intensities at different points in the region. Smenevacuundacy and 6 more users found this answer helpful.
What is non uniform electric field?
If an electric field has the same magnitude and same direction everywhere in a given space then this electric field is uniform, and if either the magnitude or direction or both change then it is a non-uniform electric field in that specified space.
What is uniform field in physics?
A field in which the value of the field strength is the same at all points. For example, a uniform electric field exists between two parallel charged plates. At the ends of the plates the field is non-uniform. Uniform magnetic fields may be produced by Helmholtz coils. From: uniform field in A Dictionary of Physics »
Is the magnetic field through the coil uniform?
Note the field is approximately uniform in between the coil pair. (In this picture the coils are placed one beside the other: the axis is horizontal.) Contours showing the magnitude of the magnetic field near a coil pair, with one coil at top and the other at bottom.
Are magnetic fields uniform?
In certainty, all magnetic fields are non-uniform, but in definite situations, we estimated the fields as being uniform (like in the center of a long coil of wire with current running through it). It is represented by convergent or divergent lines.
What is a constant magnetic field?
A wire within a constant magnetic field will always reach an equilibrium state in which there is no current in the wire. … Even if the magnetic field does not change in space (its position), it changes in the time dimension.
What does a uniform magnetic field look like?
So a uniform magnetic field would look like a bunch of parallel lines spaced out at equal distance from one another.
Where is the magnetic field most nearly uniform?
Outside a bar magnet the field lines close the loop, from north to south. The density of the field lines is proportional to the strength of the magnetic field. When a bar magnet is bend into the shape of a horseshoe, the magnetic field between the poles is nearly uniform and usually quite strong.
Is the magnetic field of a bar magnet uniform?
Answer. They r not actually uniform they are bulging at the center where the magnetic fields are weak. And towards the pole they are close and dense as at the poles the magnetic fields are maximum.
