A uniform magnetic field can be made by making a relatively long cylindrical coil. Once current is flowing through the coil a uniform magnetic field will exist all along the inside of the coil. This is not true at the very ends of the coil.
What is a uniform magnetic field?
A uniform magnetic field is one that has the same strength and direction at all points.
How is a uniform magnetic field represented?
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.26 мая 2020 г.
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.
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 densest at the center and least dense between the two poles just outside the bar magnet.
Is the magnetic field of a bar magnet uniform?
No, the magnetic field lines inside the bar magnet are non-uniform.
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 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 a magnetic field be detected?
Detecting magnetic fields
A magnetic field is invisible, but it can be detected using a magnetic compass. A compass contains a small bar magnet on a pivot so that it can rotate. The compass needle points in the direction of the Earth’s magnetic field, or the magnetic field of a magnet.
What is necessary to have a magnetic field?
If you have a rotating electric current, it will create a magnetic field. On Earth, flowing of liquid metal in the outer core of the planet generates electric currents. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around the planet.1 мая 2017 г.
Can we feel magnetic fields?
Now, research suggests that some people do indeed perceive magnetic fields, albeit unconsciously. In response to a changing magnetic field, so-called alpha brainwaves, the background “hum” of the brain, quieted in human volunteers, scientists reported yesterday (March 18) in eNeuro.
What is the weakest part of a magnetic field?
The magnetic field is weakest along the surface in the middle of the side of the magnet. This is a close-up of the field at the North pole.
Is the Earth’s core magnetic?
The core of the Earth is also an electromagnet. Although the crust is solid, the core of the Earth is surrounded by a mixture of molten iron and nickle. The magnetic field of Earth is caused by currents of electricity that flow in the molten core.
What material can block a magnetic field?
The short answer is: Any ferromagnetic metal. That is, anything containing iron, nickel or cobalt. Most steels are ferromagnetic metals, and work well for a redirecting shield. Steel is commonly used because it’s inexpensive and widely available.
