1. When the magnet of length 3cm, breadth of 1 cm and mass of 30g is used to calculate the time period of oscillation of vibration magnetometer . Calculate the moment of inertia and hence find out value of mBH ?

2. Calculate the moment of the bar magnet and horizontal intensity of earth's magnetic field when a magnet of length, breadth and mass 5cm, 2cm 40g respectively. Find the value of mBH using vibration magnetometer and m/BH using deflection magnetometer with tan A position?

3. Compare the value of m/BH with tanA, tanB and tan C position using deflection magnetometer of bar magnet and hence find out the horizontal intensity of bar magnet of 4x2 dimensions and mass of 50g ?

4. A magnet of length 6cm and breadth 3cm is used to find the horizontal intensity of earth's magnetic field at a place?

5. Calculate the moment of the bar magnet and horizontal intensity of earth's magnetic field when a magnet of length, breadth and mass 7cm, 2cm, 80g  respectively. Find the value of mBH using vibration magnetometer and m/BH using deflection magnetometer with tan B position?
