358710 A rod of length \(2\;\,m\) slides with a speed of \(5\;m\;{s^{ - 1}}\) on a rectangular conducting closed frame as shown in figure. There exists a uniform magnetic field of \(0.04\,\;T\) perpendicular to the plane of the figure. If the resistance of the rod is \(3\;\,W\). The current through the rod is

358711 Magnetic flux \(\phi\) (in weber) in a closed circuit of resistance \(10\,\Omega \) varies with time \(t(\mathrm{sec})\) as \(\phi=6 t^{2}-5 t+1\). The magnitude of induced current at \(t = 0.25\;s\) is

358712 Assertion :
An induced current is developed when the number of magnetic lines of force associated with a conductor is changed.
Reason :
Induced current gets developed in a conductor moved in a direction parallel to the magnetic field.

358713 Assertion :
Magnetic flux through the wooden ring changes with respect to time then an emf is induced in it.
Reason :
The basic difference between electric lines and magnetic lines of force is that former is discontinuous and later is continuous.
