What is tan A and tan B position of deflection magnetometer?
The magnetic field at a point along the equatorial line of a bar magnet is perpendicular to the horizontal component of Earth? s magnetic field. If the magnetometer and a bar magnet are placed in such way that this condition is satisfied, then this arrangement is called Tan B position. Deflection magnetometer.
What is Tan B position?
The magnetic field at a point along the equatorial line of a bar magnet is perpendicular to the horizontal component of Earth? s magnetic field. If the magnetometer and a bar magnet are placed in such way that this condition is satisfied, then this arrangement is called Tan B position.
How does a deflection magnetometer work?
Deflection Magnetometer works on the principle of tangent Law. According to tangent law when two uniform magnetic field act at right angles to each other on a magnetic needle, it comes to rest in the direction of the resultant field.
What is the tan law?
The laws of tangent (Law of Tan) describes the relation between difference and sum of sides of a right triangle and tangents of half of the difference and sum of corresponding angles. It represents the relationship between the tangent of two angles of a triangle and the length of the opposite sides.
What is the unit of magnetic moment?
The SI unit of a magnetic dipole moment is wb*m, and the SI unit of a magnetic moment is A*m^2 or J/Tesla.
What is a deflection magnetometer?
Deflection magnetometer is an instrument used to measure the magnetic moment and polar strength of a bar magnet. It is also used to compare the pole strengths of two bar magnet.
What is the principle of vibration magnetometer?
Vibration magnetometer works on the principle of torque and rotation in the uniform magnetic field. If the field is non-uniform or the field is very strong the magnet will not oscillate and will stop when aligned with the field. So the vibration magnetometer only works when the field is uniform and not very strong.
Is a magnetometer a vibration?
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 is tan C position?
Tan C position. The compass box alone is rotated so that the (0-0) line is parallel to the arm of the magnetometer. Then the apparatus as a whole is rotated till the aluminum pointer reads (0-0). The magnet is placed vertically on the deflection magnetometer .
What happens to the value of B if the current value is doubled?
This value is the same as that of the initial magnetic field. Which means there is no change in magnetic field if you double the current and reduce the number of turns to half. Hence the correct answer is option B.
