|
|
the force that pushes two magnets away from each other
|
|
|
an invisible region that surrounds the north pole of a magnet
|
|
|
a region around a magnet in which you can measure magnetic forces
|
Detailed explanation-1: -Answer: a region around a magnet in which you can measure magnetic forces.
Detailed explanation-2: -Magnetic field lines are imaginary lines that are used to represent the direction of magnetic field by the tangent at a point. Magnetic field lines run from north pole to south pole outside the magnet and from south pole to north pole inside the magnet. Magnetic field line never intersect.
Detailed explanation-3: -Hence, the region around a magnet where its influence can be felt is called the magnetic field.
Detailed explanation-4: -A surrounding around a magnet in which source is felt is due to magnetic property of the magnet term as magnetic field.
Detailed explanation-5: -A magnetic domain is a region within a magnetic material in which the magnetization is in a uniform direction. This means that the individual magnetic moments of the atoms are aligned with one another and they point in the same direction.
