In sum and difference method in vibration magnetometer, the time period is more if

Similar poles of both magnets are on same sides

Opposite poles of both magnets are on same sides

Both magnets are perpendicular to each other

Nothing can be said

Solution

(b)In sum position : ${T_S} = 2\pi \sqrt {\frac{{{I_s}}}{{({M_1} + {M_2}){B_H}}}} $
In difference position : ${T_d} = 2\pi \sqrt {\frac{{{I_d}}}{{({M_1} – {M_2}){B_H}}}} $
It is clear that ${T_d} > {T_s}$
