When a bar magnet is cut into two equal pieces perpendicular to its length, each piece is a magnet with _______ pole strength.
Same
Double
Half
Four times
Hence, option (A) is the correct answer.
The length of a magnet is 16 cm. Its pole strength is 250 mA−m When it is cut into four equal pieces parallel to its axis, the magnetic length, pole strength and moments of each piece are :
The magnetic moment of a bar magnet is 0.256 Am2. Its pole strength is 400 mA. It is cut into two equal pieces and these two pieces are arranged at right angles to each other with their unlike poles in contact (or like poles in contact). The resultant magnetic moment of the system is:
When a bar magnet is cut into two equal pieces along its length, we get two magnets each of _____ the pole strength
