When we use a circular coil and a cylindrical magnet the magnetic field will always be perpendicular to the area vector due to which sin wt which wil be sin90 gives 1 thus giving maximum linking of flux assosciated with the coil at any position.

{tex}\phi = \frac{q}{\epsilon}{/tex}
where, {tex}\phi{/tex} is electric flux,
q is the net charge
Since dipole has +q and -q charges
Therefore, the net charge is 0.
Therefore, {tex}\phi = \frac{0}{\epsilon}{/tex}=0

- Cyclotron is a device used to accelerate charged bodies to very high velocities (or high kinetic energies) using crossed (or mutually perpendicular) electric and magnetic fields
- Cyclotron is based on the independency of frequency (of rotation of charged particle) on the energy (velocity) and radius (of revolution) of charged particle. The motion of charge , electric field, and the magnetic field are mutually perpendicular(θ= 90°), so:
fc = 1/T = qB(sinθ)/(2πm) = qB/(2πm)
- Cyclotron is made up of 2 hollow metallic discs D1 and D2, semi-circular in shape and an oscillator.
- The discs(D) perform mainly 2 functions: a) to block(shield) electric field inside it (known as electrostatic shielding) b) act as a capacitor outside the region between the 2 discs to provide some electric field
- The oscillator’s job is to reverse the direction of electric field at the time interval of eachrevolution of charge, meaning frequency of oscillator fo should be same as the frequency of cyclotron fo.It is because when the charge moves from one D to another, the direction of electric field should always be such that the charge always accelerates(and never decelerates)

Electric flux {tex}{\phi _E}{/tex} is given by
{tex}{\phi _E} = \oint {\overrightarrow E } \cdot \overrightarrow {ds} = \frac{Q}{{{\varepsilon _0}}}{/tex}
where {tex}\theta{/tex} is total charge inside the closed surface.
{tex}\therefore{/tex} On changing the radius of sphere, the electric flux through the Gaussian surface remains same.

Therefire,on changing radius electric flux will remain same.
