GEOLOGY

Detailed explanation-1: -In electromagnetism, in general, it has been observed that ‘like repels like’. What this essentially means is that entities having the same kind of charge or poles (either positive or negative), tend to repel each other while unlike charges and magnetic poles tend to attract each other.

Detailed explanation-2: -When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. So the magnets will push apart (repel).

Detailed explanation-3: -With electricity, there are positive and negative charges. With magnetism, there are north and south poles. Similar to charges, like magnetic poles repel each other, while unlike poles attract.

Detailed explanation-4: -When two magnets are placed with their like poles facing each other, the lines of force are in opposite directions and hence like poles repel each other. When the unlike poles of a bar magnet face each other the magnetic lines of force are in the same direction and hence unlike poles attract each other.

Detailed explanation-5: -If you line the magnets up so that two of the same poles face each other, the magnets will push away. This is called repulsion.
