(AIPMT-2001)

Solution

(c) When a current is passed through the galvanomejer coil, then a magnetic fieid $B$ is produced at right angles to the plane of the coil, ie, at right angles to the horizontal component of earth's magnetic field $H.$ Under the influence of two crossed magnetic fields $\mathrm{B}$ and $\mathrm{H}$, the magnetic needle of galvanometer undergoes a deflection $\theta$ which is given by the tangent law. Using tangent law, we can find a relation

$I \propto \tan \theta$

Which clearly indicates that tangent. galvanometer is an instrument used for detection of electric current in a circuit.

A tangent galvanometer shows a deflection $45^o $ when $10\, mA$ current pass through it. If the horizontal component of the earth’s field is $3.6 \times {10^{ – 5}}\,T$ and radius of the coil is $10\, cm$. The number of turns in the coil is……$turns$

medium

A vibration magnetometer consists of two identical bar magnets placed one over the other such that they are mutually perpendicular and bisect each other. The time period of oscillation in a horizontal magnetic field is $4\, sec$. If one of the magnets is taken away, find the period of oscillation of the other in the same field (in $sec.$) :-

Two tangent galvanometer coils of same radius connected in series. The current flowing produces deflection of $60^o$ and $45^o$. The ratio of number of turns in coil is

medium

A tangent galvanometer has $80$ turns of wire. The internal and external diameters of the coil are $19 \,cm$ and $21 \,cm$ respectively. The reduction factor of the galvanometer at a place where $H=0.32$ oersted will be $(1$ oersted $=80 \,A / m )$
