Choose the wrong statement
• A
magnetic poles always exist in pairs
• B
magnetic poles are always of equal strengths
• C
like poles repel each other
• D
unlike poles repel each other

#### Solution

Magnetic monopoles do not exist, unlike charges, where solo charges can exist. This means that magnetic poles always exist in pairs. Also the poles have equal strengths, that is, both north and south poles have equal strength.
Like poles attract each other and unlike poles attract each other.
