Where is the field the strongest where is it the weakest?
Field-Line Patterns The relative magnitude of the electric field is proportional to the density of the field lines. Where the field lines are close together the field is strongest; where the field lines are far apart the field is weakest. If the lines are uniformly-spaced and parallel, the field is uniform.
Where is any magnetic field strongest?
the poles
The magnetic field is strongest at the poles, where the field lines are most concentrated. Field lines also show what happens to the magnetic fields of two magnets during attraction or repulsion.
Where is the magnetic field the strongest and why?
the magnetic field lines never cross each other. the closer the lines, the stronger the magnetic field (so the magnetic field from a bar magnet is strongest closest to the poles)
Where are the magnetic fields strongest near a bar magnet?
poles
The strongest external magnetic fields are near the poles. A magnetic north pole will attract the south pole of another magnet, and repel a north pole. The magnetic field lines of a bar magnet can be traced out with the use of a compass.
Which magnet is strongest?
neodymium
The strongest permanent magnets in the world are neodymium (Nd) magnets, they are made from magnetic material made from an alloy of neodymium, iron and boron to form the Nd2Fe14B structure.
Where is Earth’s magnetic field weakest?
the equator
Intensity: The magnetic field also varies in strength over the earth’s surface. It is strongest at the poles and weakest at the equator.
What is the magnetic field around a bar magnet?
A magnetic field is the region around a magnet where a force acts on another magnet or on a magnetic material.
Which is the weakest magnet?
bar magnet
The north pole of one magnet attracts the south pole of another magnet. A bar magnet is considered as the weakest magnets because the poles have the smallest area.
Which shape of magnet is the weakest?
This is due to coercivity also known as the “staying magnetized” ability of a given magnet. Coercivity is weaker in disc or ring shapes, slightly stronger in cylinder or bar shapes, and strongest in horseshoe shapes. To increase the coercivity of horseshoe magnets, steel keepers or magnet keepers are used.
Is Earth’s magnetic field weak?
Earth’s magnetic field, which protects it from solar radiation, has a weak spot that’s expanding. This weak spot may be caused by pieces of an ancient planet that hit Earth and sank into the mantle.
Is the Earth magnetic field strong or weak?
The magnetic field strength at the Earth’s magnetic equator is 0.0000305 tesla, or 0.305 x 10-4 T. Maps of the surface magnetic fields of Earth show stronger fields near the poles where the magnetic field lines congregate, at roughly twice the strength of the field at the equator.
