This choice is accurate since both electric and magnetic fields can be created by a fluctuating current. Because current charges move in a unit of time, an electrical field and a magnetic field are created around the charges as a result of their motion.

The SI unit for flux density or magnetic field induction is Weber/m2 or Tesla (T).

Eddy currents start to flow in a conductor when it is exposed to a fluctuating magnetic field. Swirling currents that travel in closed loops perpendicular to the magnetic field plane within a conductor are known as eddy currents.

Given: L = 15 cm = 0.15 m is the length.
N = 300 is the number of turns.

Present = I = 5 A
Free space permittivity = μo = 4π × 10-7
B = magnetic field =?
Answer:
n = 300 / 0.15 = 2000 turns per meter is the number of turns per unit length.
As is well known:
B = μonl = 4π × 10-7 × 2000 × 5 = 1.37 × 10-2 W/m²

The number of magnetic field lines per unit area is known as the magnetic flux density.

Magnetic field = magnetic flux density

Magnetic flux divided by area is the magnetic flux density.

B = Φ / A

A stands for area, B for magnetic flux density, and Φ for magnetic flux.

Since the flux change is negative, the answer should be C because negative times negative equals positive.

q x v x B x sin(θ) ; where sin 45 is equal to 1/✓2

Putting the values together yields 4eB/✓2, or 2✓2 eB.( 4/✓2 = 2✓2).

Magnetic flux=BA cos θ
It is positioned in the “x-y plane,” as the question indicates, suggesting that the coil and magnetic field are at a 90-degree angle. As a result, cos theta would have zero value. As a result, there would be no magnetic flux.
