A uniform magnetic field is represented by equally spaced parallel straight lines. The direction of the flux is the direction in which the north-seeking pole of a small magnet points. The lines of flux are continuous, forming closed loops.
What is a 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.
Where is a uniform magnetic field?
A uniform magnetic field is a circumstance where the magnetic field lines are moving from North to the South Pole of a magnet with a uniform severance and they are peripatetic in a straight line, this is not probable to acquire with a single stable magnet.
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.
What is a magnetic field diagram?
The magnetic field is described mathematically as a vector field. This vector field can be plotted directly as a set of many vectors drawn on a grid. Each vector points in the direction that a compass would point and has length dependent on the strength of the magnetic force.
How can you tell where the magnetic field is strongest?
The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.
Where is the magnetic field strongest?
The magnetic field is strongest at the center and weakest between the two poles just outside the bar magnet. The magnetic field lines are least dense at the center and densest between the two poles just outside the bar magnet.
How do you create 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.
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.
What are the 4 magnetic metals?
Magnetic metals include:
- Some alloys of rare earth metals.
What is the largest possible magnitude of the force on the electron due to the magnetic field?
The maximum magnitude of the magnetic force acting on the electron when its velocity v is perpendicular to B is Fmag = evB. Details of the calculation: Fel = kee2/r2 = (9*109* (1.6*10-19)2/(0.53*10-10)2) N = 8.2*10-8 N.
Can you see a magnetic field?
A magnet creates a magnetic field around it. You cannot see a magnetic field, but you can observe its effects. A force is exerted on a magnetic material brought into a magnetic field. The force is a non-contact force because the magnet and the material do not have to touch each other.
What is meant by magnetic field?
A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. … Magnetic fields surround magnetized materials, and are created by electric currents such as those used in electromagnets, and by electric fields varying in time.
What exactly is a magnetic field?
The magnetic field is the area around a magnet that has magnetic force. All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other.
