Two different coils have self-inductance $L_1 = 8 \, mH$ and $L_2 = 2 \, mH$. The current in both coils is increased at the same constant rate. At a certain instant of time,the power supplied to the two coils is the same. At that time,the current,induced voltage,and energy stored in the first coil are $i_1, V_1$,and $W_1$ respectively. Corresponding values for the second coil at the same instant are $i_2, V_2$,and $W_2$ respectively. Then:

  • A
    $\frac{i_1}{i_2} = \frac{1}{4}$
  • B
    $\frac{V_2}{V_1} = \frac{1}{4}$
  • C
    $\frac{W_2}{W_1} = 4$
  • D
    All of the above

$A$ circular coil of $500$ turns of wire has an enclosed area of $0.1\,m^2$ per turn. It is kept perpendicular to a magnetic field of induction $0.2\,T$ and rotated by $180^o$ about a diameter perpendicular to the field in $0.1\,s$. How much charge will pass when the coil is connected to a galvanometer with a combined resistance of $50\,\Omega$?

$A$ metallic ring of mass $m$ and radius $l$ (ring being horizontal) is falling under gravity in a region having a magnetic field. If $z$ is the vertical direction,the $z$-component of the magnetic field is $B_z = B_0(1 + \lambda z)$. If $R$ is the resistance of the ring and the ring falls with a velocity $v$,find the energy lost in the resistance per unit time. If the ring has reached a constant velocity,use the conservation of energy to determine $v$ in terms of $m, B_0, l, \lambda, R$ and acceleration due to gravity $g$.

View Solution

When a coil is placed in a time-dependent magnetic field,the power dissipated in it is $P$. The number of turns,area of the coil,and radius of the coil wire are $N, A$,and $r$ respectively. For a second coil,the number of turns,area,and radius are $2N, 2A$,and $3r$ respectively. When the first coil is replaced with the second coil,the power dissipated in it is $\alpha P$. The value of $\alpha$ is . . . . . . .
