GEOLOGY

Detailed explanation-1: -We cannot make a magnet with only one pole. Any magnet has always two poles namely north and south.

Detailed explanation-2: -Magnetic poles always occur in pairs, north pole and south pole. It is impossible to obtain a magnet having only one pole.

Detailed explanation-3: -(i) A cylindrical magnet has only one pole. (ii) Artificial magnets were discovered in Greece. (iii) Similar poles of a magnet repel each other. (iv) Maximum iron filings stick in the middle of a bar magnet when it is bought near them.

Detailed explanation-4: -Thus, we can conclude that any piece of magnet necessarily has got two poles, North and South without any exception. Hence, the above statement that the cylindrical magnet has only one false is entirely false.

Detailed explanation-5: -Well bar magnets have two poles, so their magnetic fields are called dipole which means–you guessed it–two poles! But some magnets have more than two poles. In fact, some have four, or six, or even eight!
