Both these questions go together Solution When we bring a magnet near a metal, the metal enters a magnetic field, all of the electrons inside the metal \"line up,\" causing a temporary magnetic alignment that is attracted to the magnet . That alignment dissipates once the magnetic field is removed and therefore, the only way for a metal to be repelled by a magnet is if it\'s first magnetized to the opposite pole. so if the metal is magnetised and the a magnet with the same pole is brought near it will repel Note:- its easy to magnetise a iron piece just rub the magnet over the metal in one direction many, many times. By rubbing a magnet over your metal continuously, you are aligning the electrons in the metal in a certain way, toward a certain polarity.

Solution
When we bring a magnet near a metal, the metal enters a magnetic field, all of the electrons
inside the metal "line up," causing a temporary magnetic alignment that is attracted to the
magnet . That alignment dissipates once the magnetic field is removed and therefore, the only
way for a metal to be repelled by a magnet is if it's first magnetized to the opposite pole.
so if the metal is magnetised and the a magnet with the same pole is brought near it will repel
Note:- its easy to magnetise a iron piece just rub the magnet over the metal in one direction
many, many times. By rubbing a magnet over your metal continuously, you are aligning the
electrons in the metal in a certain way, toward a certain polarity. The more that you do this, the
longer the effect will last, taking more time for the electrons to return to their random or
unpolarized state.
so the answer to the question is 1) c
2) d
