The electric field and magnetic field components of an electromagnetic wave going through vacuum is described by
$$\mathrm{{E_x} = {E_o}\sin (kz - \omega t)}$$
$$\mathrm{{B_y} = {B_o}\sin (kz - \omega t)}$$
Then the correct relation between E$$_0$$ and B$$_0$$ is given by
A metallic rod of length 'L' is rotated with an angular speed of '$$\omega$$' normal to a uniform magnetic field 'B' about an axis passing through one end of rod as shown in figure. The induced emf will be :
A conducting circular loop of radius $$\frac{10}{\sqrt\pi}$$ cm is placed perpendicular to a uniform magnetic field of 0.5 T. The magnetic field is decreased to zero in 0.5 s at a steady rate. The induced emf in the circular loop at 0.25 s is :
In $$\overrightarrow E $$ and $$\overrightarrow K $$ represent electric field and propagation vectors of the EM waves in vacuum, then magnetic field vector is given by :
($$\omega$$ - angular frequency) :
