Questions + Answers key
Take MCQ Physics Test1.
The magnetic field lines prefer to pass through iron than why?
2.
What is magnetic Lorentz force?
3.
In what way is the behaviour of a diamagnetic material different from that of a paramagnetic when kept in an external magnetic field?
4.
State the factors on which the current sensitivity of a galvanometer is increased.
5.
Define Voltage sensitivity?
1.
The magnetic field lines prefer to pass through iron than because the permeability of iron is much larger than air.
2.
The material having +ve and small susceptibility is paramagnetic material.
(i) They have a tendency to move from weaker to stranger parts of the field.
(ii) Susceptibility is inversely proportional to the temperature.
3.
A diamagnetic substance would move towards the weaker region of the field while a paramagnetic substance would move towards the stronger region.
4.
(i) The number of turns N.
(ii) The magnetic induction B.
(iii) The area of coil A.
5.
It is defined as the deflection produced per unit voltage applied across the galvanometer.
Vs =\(\frac { \theta }{ V } \)
Vs = \(\frac { \theta }{ IR_{ g } } =\frac { NAB }{ KR_{ g } } =V_{ s }=\frac { 1 }{ GR_{ g } } =\frac { { I }_{ s } }{ { R }_{ g } } \)
