By convention, the field direction is taken to be
outward from the North pole and in to the South pole of the magnet
. Permanent magnets can be made from ferromagnetic materials. As can be visualized with the magnetic field lines, the magnetic field is strongest inside the magnetic material.
What is the direction of magnetic field inside a bar magnet?
(a) The direction of magnetic field lines outside a bar-magnet is from North seeking pole to south seeking pole while inside the magnet it is
from south to north seeking pole
.
What is the direction of magnetic field in bar magnet class 10?
North pole to south pole
is the direction of magnetic field lines outside a bar-magnet. The magnetic field is the strongest inside the magnetic material. 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.
What is the direction of magnetic fields?
The direction of magnetic field lines is defined to be the
direction in which the north end of a compass needle points
. The magnetic field is traditionally called the B-field.
Is there a uniform magnetic field inside a bar magnet?
No, the magnetic field lines inside the bar magnet are
non-uniform
. They are curved in the nature.
Is the magnetic field uniform inside a bar magnet?
Because the magnetic field lines are a parallel and goes from South to North inside the bar magnet. And also the concentration of field lines is
uniform inside
the bar magnet and higher at the edges.
How can you tell when a magnetic field is the 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 are the magnetic fields strongest near a bar magnet?
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
)
Does a compass point to geographic North Pole?
Earth’s magnetic north pole is near Earth’s geographic south. That’s why the north pole of a
compass points toward north
because that’s where Earth’s south magnetic pole is located and they attract.
What is the direction of force?
The direction of the force is
in the direction opposite the object’s direction of motion
. When the interaction ceases, the two objects no longer experience the force. The direction of the force is perpendicular to the direction the object moves. Forces only exist as a result of an interaction.
How do you determine the direction of an electric field?
The direction of the electric field is
always directed in the direction that a positive test charge would be pushed or pulled if placed in the space surrounding the source charge
. Since electric field is a vector quantity, it can be represented by a vector arrow.
Where is magnetic field strength uniform in a bar magnet?
In the case of a bar magnet, A bar magnet produces a non-uniform magnetic field that can be seen by the magnetic lines of force arising from
the north pole of the magnet and progressing towards the south pole of the magnet
.
Is the field around the bar magnet uniform or non-uniform Why?
The magnetic field due to a bar magnet is
non-uniform
. The magnetic field in an area is non-uniform if it has dissimilar magnetic intensities at diverse points in the area.
What will happen when a magnetic needle is kept in a non-uniform magnetic field?
Magnetic needle is placed in non-uniform magnetic field. It
experiences force and torque both due to unequal forces acting on poles
.
Why the magnetic force is not uniform in any magnet?
Because
each dipole is effected by the magnetic that exist in its positions
, if the magnetic field is non-uniform then the forces on the north pole and on the south pole won’t be equal and the magnet will experience a total force different from 0.
