Following Basic Science multiple choice objective type questions and answers will help you in many types of 2024 job and other entrance examinations :

1.The deflection magnetometer works on the principle of
Coulomb’s law
Biot-savart law
Tangent law
Ampere law

2.A coil of 100 turns and area 0.5 m2 has its plane perpendicular to a uniform magnetic field of induction 0.2m Wb/ m2.Then magnetic flux through the coil is
zero
0.1 Wb
1 Wb
10 Wb

3.During the initial adjustment, the pointer of the deflection magnetometer in TanA position.
points East – West direction
points North – South direction
is perpendicular to magnetic meridian
is along the arms

4.in a coil of radius r and having n turns the intensity of magnetic field produced by current of I A is
H = n I/2r2
H = n I/2r
H = 2r/n I
H = n I/2

parallel to the magnetic meridian
along the magnetic meridian
perpendicular to the magnetic meridian
along the equator
