Two bar magnets are bound side by side, and are suspended so as to swing once in 12 s when like poles are together. When the direction of one of the magnets is reversed, the combination makes 3.75 vibrations per minute. Compare the magnetic moments of the two magnets.

Two bar magnets are bound together side by side and suspended. They swing in 12s when their like poles are together and in 16s when their unlike poles are together, the magnetic moments of these magnets are in the ratio

The time period of viberation of two magnets in sum position (magnets placed with similar poles on one sides one above the other) is 3s. When polarity of weaker magnet is reversed the combination makes 12 oscillations per minutes. What is the ratio of magnetic moments of two magnets?

Two bar magnets placed together in a vibration magnetometer take 3 seconds for 1 vibration. If one magnet is reversed, the comnination takes 4 seconds for 1 vibration. Find the ration of their magnetic moments.

The combination of two bar magnets makes 10 oscillations per second in an oscillation magnetometer when like poles are tied together and 2 oscillations per second when unlike poles are tied together. Find the ratio of the magnetic moments of the magnets. Neglect any induced magnetism.

Two bar magnets are kept togethe and suspended freely in earth's magntic field . When both like poles are aligned , the time period is 6 sec. When opposite poles are aligend , the time period is 12 sec . The ratio of magnetic moments of the two magnets is .

when the wire loop is rotated in the magnetic field between the poles of a magnet the direction of emf changes once in every

The direction of the null points is on the equatorial line of a bar magnet, when the north pole of the magnet is pointing

The length, breadth and mass of two bar magnets are same but their magnetic moments are 3M and 2M respectively. These are joined pole to pole and are suspended by a string. When oscillated in a magnetic field of strength B, the time period obtained is 5s. If the poles of either of the magnets are reverse then the time period of the combination in the same magnetic field will be –
