The magnetic field lines start at a magnet's north pole and end at the south pole.
A. They begin on north poles and end on south poles.
<u>Explanation:</u>
Magnetic field lines are a visual instrument used to speak to attractive fields. They portray the bearing of the attractive power on a north monopole at some random position. The north post of one magnet draws in the south shaft however repulses the north shaft of another magnet dissimilar to shafts pull in and like shafts repulse.
A metal is a magnet on the off chance that it repulses a known magnet. Be that as it may, the Magnetic field lines don't simply end at the tip of the magnet. They go directly through it so that inside the magnet the attractive field focuses from the south shaft toward the north post.
Answer:
d
Explanation:
The minimum energy configuration in electrostatics states that Charges always reside on the surface of a conductor. If anyhow they were inside, an electric field would exist inside and would act to move them to the surface,
Therefore, the drawing that shows where the charges reside when they are in equilibrium is a hollowed-out "hole" in the interior of the circle, with positive signs surrounding the exterior edge. This means that the d part is the correct answer.
C, all cells contain chloroplast, is not part of the cell theory.
