where on a magnet is the magnetic force the minimum
Answers
Answer:
The strength of a magnet is minimum in the middle and maximum at its ends.
Explanation:
Magnetic Field
A magnetic field is an area where a magnet makes an effect.
Magnetic Field Lines
Magnetic field lines are imaginary lines around a magnet.
The strength of the magnetic field at a certain point depends on the linear density of the magnetic force of the lines at that point, which means that the magnetic force of the lines is full, then the magnetic field at that point is strong and opposite.
Because all lines of force in a magnetic field originate from the poles of a magnet, and the density of lines of force in a magnetic field depends on the distance from the pole. As the distance from the pole increases, the magnetic force density of the lines decreases.
Therefore, the magnetic force of the lines is more at the poles than in the center of the magnet, and thus the strength of the magnetic field at the north and south poles of the magnet is greater than in the center of the magnet.
Therefore, the strength of a magnet is minimum in the middle and maximum at its ends.
