What is the use of vibration magnetometer?
Vibration magnetometer is used for comparison of magnetic moments and magnetic fields. This device works on the principle, that whenever a freely suspended magnet in a uniform magnetic field, is disturbed from it’s equilibrium position, it starts vibrating about the mean position.
What does a deflection magnetometer measure?
Deflection magnetometer is an instrument used to measure the magnetic moment and polar strength of a bar magnet.
What is the principle of vibration magnetometer?
This device works on the principle, that whenever a freely suspended magnet in a uniform magnetic field, is disturbed from it’s equilibrium position, it starts vibrating about the mean position. In short we can say vibration magnetometer works on the principle of torque acting on the bar magnet.
What is the value of BH?
At a place on earth the value of BH is 0.1732 oersted and angle of dip is 30°.
What is the pole strength?
Definition of pole strength : a quantity corresponding to the amount of magnetic flux emanating from a given magnetic pole and expressed in terms of the unit magnetic pole.
What are the types of magnetometer?
There are two basic types of magnetometer measurement. Vector magnetometers measure the vector components of a magnetic field. Total field magnetometers or scalar magnetometers measure the magnitude of the vector magnetic field.
What is BH and BV?
Horizontal and vertical components of earth’s magnetic field are Bh and Bv, respectively. We know that Bh=B cosδ where B is the earth’s total magnetic field and δ is the angle of dip. Also, Bv=Bsinδ
What is angle of dip?
The dip angle, I (for inclination), is the angle that the total field vector makes with respect to the horizontal plane and is positive for vectors below the plane. It is the complement of the usual polar angle of spherical coordinates.
What is the unit of pole?
Definition of unit magnetic pole : a unit of magnetic pole strength equal to the strength of a magnetic pole that repels an identical pole at a distance of one centimeter with a force of one dyne.
What is SI unit of pole strength?
Pole strength is given by m=M/2l. Unit of magnetic dipole moment is Am2. Therefore, unit of pole strength will be Am.
What is SI unit of magnetic moment?
unit of magnetic moment is Weber.
