B.A. = magnetic flux

The dot product of the magnetic field and the area perpendicular to the field is known as magnetic flux.

For magnetic flux, options B, C, and D are inappropriate.

A “time base generator” is the circuit that supplies voltage to X-plates. This kind of electronic circuit is utilized in electronic displays like television sets and oscilloscopes. In a CRO (Cathode Ray Oscilloscope), the electron beam’s horizontal deflection is controlled by a sawtooth waveform produced by the time base generator. This makes it possible to display signals that change over time, like waveforms and pictures.

In a uniform magnetic field, the radius of an electron’s circular orbit is determined by:

(mv)/(Be) = r

Where,

m = electron mass

v = electron velocity

B is the strength of the magnetic field.

e = electron charge

The radius and velocity are directly proportional because the electron’s mass, charge, and magnetic field are all constant.

The radius will likewise double if the velocity doubles.

Therefore, if the orbit’s initial radius is 2 cm, it will double to 4 cm after the speed is doubled.

Thus, 4 cm is the response.

The magnetic field that surrounds any wire carrying current is B = µ0I/2πr. The equation above shows that the magnetic field is directly proportional to the current and inversely proportional to the distance. The magnetic field will decrease by a factor of two, or 1.5 T, when the distance from the wire doubles.

Cathode Ray Oscilloscopes (CROs) use the oscillation principle to create and show electrical waveforms on a screen. It is not, however, a CRO working principle.A Cathode Ray Oscilloscope (CRO) uses an electron beam to show electrical waveforms on a screen as part of its operation. Therefore, none of these is the right choice.

The speed of light is equal to the photon velocity. Although photons have no mass, their energy is E = hf = hc/λ. Planck’s constant is h = 6.626*10-34 Js in this case. The electromagnetic wave’s wavelength and photon energy are inversely correlated.

E=6.626×10−34 × 3×108​/1240×10-9 ≈ 1.00 eV.

The number of turns in a coil directly correlates with the magnetic flux associated with it. Each turn of a coil adds to the magnetic flux when it has several turns. A coil’s connection to magnetic flux increases with its number of turns.
