At a certain place, a magnet makes 30 oscillations per minute. At another place, the magnetic field is double. What is the its time period ?

At a certain place a magnet makes 30 oscillations per minute. At another place where the magnetic field is double, its time period will be

A magnet makes 10 oscilllations per minute at a place where the angle of dip is 45^(@) and the total intensity is 0.4 gauss. The number of oscillations made per sec by the same magnet at another place where the angle of dip is 60^(@) and the total intensity 0.5 gauss is approximately.

A magnet freely suspended in a vibration magnetometer makes 10 oscillations per minute at a place A and 20 oscillations per minute at a place B. If the horizontal component of earth's magnetic field at A is 36xx10^(-6)T , then its value at B is

A magnet makes 30 vibrations per minute at a place, where horizontal component of earth's field is 0.18G. At another place if it takes 1.6s to complete one vibration. What is the value of horizontal component of earth s field there? What is the magnetic moment if its moment of inertia is 10^-5 kg m^2 ?
