Magnetism is a size independent propert. If an object is magnetic or not does not depend on the size of the object.
In an electric current.
The shape of the electric field is altered. The fields will react by either repelling or attracting each other.
Simple Answer:The shape of the magnetic field of a uniformly wound solenoid is very nearly identical to the field produced by a uniformly magnetized permanent magnet with the same physical shape as the solenoid.For the Experts:This is a consequence of the mathematical equivalence of the source of the magnetic field as created by a current and the source of a magnetic field as created by the curl of the magnetization density of permanent magnet.
Simple: chalk dust has no magnetic properties whatsoever, and is an insulator. As such, the magnetic field will flow right past it as if it weren't there, so it cannot position itself accordingly.
The further the magnets, the lesser the attraction/repulsion.
the magnetic field is an oblong shape with two points at the north and south!!
I'm not sure what "shape" means as applied to a magnetic field, which is not a physical object. To the extent I can conceive of them having a shape, the shape depends on the shape of the magnet, or more precisely upon the geometry of the poles of the magnet.
Magnetism is a size independent propert. If an object is magnetic or not does not depend on the size of the object.
Yes. I can be done using iron filings and a clear piece of plastic. Pour on the iron filings, put on the plastic, and then the magnet. The iron filings should form the shape of the magnetic field around it. If that does not work, here is a link to a picture... http://www.fi.edu/htlc/teachers/lettieri/magneticfields.jpg Hope that helps.

Just a hypothesis: Cylindrical shape with cone shape combined in special array. Made of electric coils and permanent magnets.
A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials and attracts or repels other magnets. A refrigerator magnet is an ornament attached to a magnet that is used to post items such as shopping lists or report cards on a refrigerator, or simply as decoration. Refrigerator magnets come in a wide variety of shapes and sizes, including for example, images die-cut to a specific shape or tiny plastic sculptures of fruits. Refrigerator magnets are a relatively popular object of collectors.
a circle. using your right hand, if you point your thumb in the direction of the current, your fingers will curl around the wire in the shape of the magnetic field.
Fringing effect is the magnetic characteristic caused by the shape around directly opposing the magnetic surfaces.
FRINGING EFFECT:Fringing effect is the magnetic characteristic caused by the shape around directly opposing the magnetic surfaces.
