The length of a magnet is large compared to its width and breadth. The time period of its oscillation in a vibration magnetometer is ` 2 s`. The magnet is cut along its length into three equal parts and these parts are then placed on each other with their like poles together . The time period of this combination will be

The length of a magnet is large compared to its width and breadth. The time period of its oscillation in a vibration magnetometer is 150 ms. The magnet is cut along its length into three equal parts and three parts are then placed on each other with their like poles toghether. The time period of this combination (in ms) will be

The length of a magnet is large compared to its width and breadth. The time period of its oscillation in a vibration magnetometer is T. The magnet is cut along its length into three parts and these parts are then placed together. The time period of this combination will be

The length of a magnet is large compared to its width and breadth. The time period of its oscillation in a vibration magnetometer is T. The magnet is cut along its length into six parts and these parts are then placed togather as shown in the figure. The time period of this combination will be

If a permanent bar magnet is cut along its length into two equal parts, what will be the pole - strength and magnetic moment of each part ?

With a standard rectangular bar magnet of length (l), breadth (b,bltlt) and magnetic moment M, the time period of the magnet in a vibration magnetometer is 4 s. If the magnet is cut normal to its length into four equal pieces, the time period (in second) with one of the piece is

The time period of a bar magnet oscillating in a uniform magnetic field is 3 seconds. if the magnet is cut into two equal parts along the equatorial line of the magnet and one part is made to vibrate in the same field, what is the time period ?

With a standard rectangular bar magnet the time period of a vibration magnetometer is 4 s. The bar magnet is cut parallel to its length into four equal pieces. The time period of vibration magnetometer when one piece is used (in second) (bar magnet breadth is small) is
