Vedclass · Answer

(A) When a magnet falls through a closed coil,the changing magnetic flux through the coil induces an electromotive force $(EMF)$ and a current in the coil,according to Faraday's law of induction.According to Lenz's law,the direction of this induced current is such that it creates a magnetic field that opposes the change in magnetic flux that produced it.As the magnet falls,the induced current creates a magnetic force that acts upwards on the magnet,opposing its downward motion.Because there is an upward force acting against the gravitational force $(mg)$,the net downward force on the magnet is $F_{net} = mg - F_{magnetic}$.Since $F_{net} Therefore,both statements are true,and Statement $-2$ is the correct explanation for Statement $-1$.

Statement $-1$: When a magnet is made to fall freely through a closed coil,its acceleration is always less than acceleration due to gravity $(g)$.
Statement $-2$: Current induced in the coil opposes the motion of the magnet,as per Lenz's law.

The formula for induced $e.m.f.$ in a coil due to change in magnetic flux through the coil is (here $A$ = area of the coil,$B$ = magnetic field).

$A$ coil having $100$ turns and an area of $1 \times 10^{-3} \ m^2$ is placed in a magnetic field of $1 \ Wb/m^2$. If the magnetic field is reversed,what is the total charge that flows through the circuit,given that the resistance of the circuit is $10 \ \Omega$?

$A$ coil of resistance $400\,\Omega$ is placed in a magnetic field. If the magnetic flux $\phi$ (in $Wb$) linked with the coil varies with time $t$ (in $s$) as $\phi = 50t^2 + 4$,the current in the coil at $t = 2\,s$ is $..........\,A$.

As shown in the figure,a bar magnet is moving towards a stationary coil with a constant speed $v$. The direction of the induced current in the coil as observed by the observer on the $R$.$H$.$S$. is . . . . . . .
