Detailed explanation-1: -attract each other. as in the case of unlike magnetic poles unlike electric charges? static electricity.

Detailed explanation-2: -As in the case of unlike magnetic poles, unlike electric charges attract each other.

Detailed explanation-3: -Unlike poles of different magnets attract each other; like poles repel each other.

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: -Electric charge comes in two varieties, which we call positive and negative. Like charges repel each other, and unlike charges attract each other. Thus, two positive charges repel each other, as do two negative charges.
