Can someone reword this? a magnetic substance has magnetic fields. these fields start at the north pole wrap around the magnet, and terminate at the south pole of the magnet. all magnetic substances have north and south poles

It's basically saying that everything magnetic has two magnetic poles. They start at the north pole and end at the south pole. All magnetic substances have north and south magnetic poles.

a chemical reaction

explanation:

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
