How do similar (s-s or n-n) magnetic poles interact?

Explanation:

Magnet has two poles: (1) North pole and (2) South pole.

Like poles repel each other. If the like poles are interacting each other then there will be force of repulsion in between these poles.

Unlike poles attract each other. If the unlike poles are interacting each other then there will be force of attraction in between these poles.

S-S and N-N magnetic poles repel each other.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
