A magnet of magnetic moment `M` oscillating freely in earth's horizontal magnetic field makes n oscillations per minute. If the magnetic moment is quadrupled and the earth's field is doubled, the number of oscillations mode per minute would be

When a bar magnet is placed at some distance along the axis of the magnetic needle of an oscillation magnetometer located in earth's magnetic field, the needle makes 14 oscillaitons per minute. If the bar magnet is turned so that its poles exchange their positions, the needle makes 20 oscillations per minute. If the magnet is completely removed, the frequency of the needle is nearly ("assuming"BgtB_(H) "at needle")

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

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

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

The magnetic needle of a vibration magnetometer makes 12 oscillations per minute in the horizontal component of earth's magnetic field. When an external short bar magnet is placed at some line, it makes 15 oscillations per minute, If the poles of the bar magnet are interchanged, the number of oscillations it makes per minute is

A magnet takes a minute to make 30 oscillations in a magnetic field. If the strength is doubled, then the time period of oscillation (in S) is

The frequency of oscillation of the magnet in an oscillation magnetometer in the earth's magnetic field is 40 oscillations per minute. A short bar magnet is placed to the north of the magnetometer, at a separation of 20cm from the oscillating magnet, with its north pole pointing towards north (figure). The frequency of oscillation is found to increase to 60 oscillations per minute. Calculate the magnetic moment of this short bar magnet. Horizonatl component of the earth's magnetic field is 24 muT .
