deflection magnetometer experiment pdf

This experiment first measures the horizontal component, ! h. The direction of ! h is towards magnetic north and determines the direction a compass points. Measurement of ! h will be done by the deflection magnetometer method (sometimes called the tangent magnetometer method). A known magnetic field, ! coil

In this experiment we shall draw M-H curve using deflection magnetometer and a thin rod shaped specimen of iron placed along the axis of a solenoid. As such, you will be required to measure solenoid current i and deflection 0 of the tiny magnet in the magnetometer. So it is

magnetometer and vibration magnetometer. Apparatus: - Deflection magnetometer with compass, vibration magnetometer, bar magnet, brass rod, stop watch. Formula: - (a)Determination of using deflection magnetometer d = distance from the center of the needle to the center of the magnet. l = half the length of magnet (b) Determination of MH using ...

Then the magnetometer is rotated till pointer reads (0-0). Finally, the bar magnet (the same one that was previously suspended in the Vibration Magnetometer) is placed horizontally, parallel to the arm of the deflection magnetometer, at a distance d chosen so that the deflection of the aluminum pointer is between 30° and 60°.

S. (b) Fig. 2.6: Marking magnetic meridian: a) Chalk marks corresponding to the ends of the pointer depict east-west; b) the magnetic meridian is normal to the east-west line. 3. Rotate the magnetometer slowly in its groove so that the ends of the needle of the compass read zero-zero on the circular scale. 4.

Then the magnetometer as a whole is rotated till pointer reads (0-0). Finally, the bar magnet (the same one that was previously suspended in the Vibration Magnetometer) is placed horizontally, parallel to the arm of the deflection magnetometer, at a distance d chosen so that the deflection of the aluminum pointer is between 30° and 60°.

5. Experiment Aim: Study of magnetic shielding using deflection magnetometer. Apparatus required: A small bar magnet, deflection magnetometer and a hollow ferromagnetic material (iron or steel). Formula Magnetic field strength, F = H tan θ Am-1 Where, F = Magnetic field strength of the bar magnet at the point of magnetometer needle

The experiment is repeated for different values of d and an average value for m/B H is calculated using equation(7). Tan B position. The compass box alone is rotated so that the (90-90) line is parallel to the arm of the magnetometer. Then the magnetometer as a whole is rotated so that the pointer reads (0-0).

3.1 Flip Coil Method. You will determine the magnetic field of the circular magnet using the flip coil technique. Construct an integrator circuit (refer to Figure 5) for use with the flip coil. Note that according to Equation 15 the output voltage is proportional to 1/RC, so a small value of RC is preferred.
