A bar magnet is oscillating in the earth’s magneticfield with a period T. What happens to its periodof motion, if its mass is quadrupled [1994, 03]
  • a)
    motion remains simple harmonic with newperiod = T/2
  • b)
    motion remains simple harmonic with newperiod = 2 T
  • c)
    motion remains simple harmonic with newperiod = 4T
  • d)
    motion remains simple harmonic and theperiod stays nearly constant
Correct answer is option 'B'. Can you explain this answer?

The time period of a bar magnet in a magnetic field is given by.
Here, I = moment of inertia ∝ m , M = moment of magnet, B = magnetic field.
, so, T becomes twice as mass becomes four times

A bar magnet is oscillating in the earth’s magneticfield with a ...
's magnetic field. The oscillation of the bar magnet depends on the orientation of the magnet with respect to the magnetic field of the earth. When the bar magnet is aligned with the earth's magnetic field, it experiences minimal resistance and oscillates freely. However, when the magnet is oriented perpendicular to the earth's magnetic field, it experiences maximum resistance and oscillates with a decreased amplitude.

The oscillation of the bar magnet in the earth's magnetic field is similar to the oscillation of a pendulum. The magnet oscillates back and forth around its equilibrium position, which is the direction of the earth's magnetic field. The frequency of the oscillation depends on the strength of the magnetic field and the mass of the bar magnet.

The oscillation of the bar magnet in the earth's magnetic field has many practical applications. For example, it can be used to measure the strength and direction of the earth's magnetic field, which is important for navigation and geophysical research. It can also be used as a simple model for understanding the behavior of more complex magnetic systems, such as magnetic materials and devices.
