A magnetic field. that's how people make magnets, by wrapping copper wire around whatever they want to be magnetic then running electricity through the wire. it works on revers to make electricity.

<span>A linearly polarized electromagnetic wave has an average intensity of 450 W/m2. This wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). Polarizer A is oriented with its transmission axis at an angle of θ1 = 32.6° with the incident electric field. Polarizer B has its axis at an angle of θ2 = 75.8° with the incident electric field, as shown in the figure.</span>
Answer:
e = 10 V
Explanation:
given,
number of the coaxial loops = 10
Cross sectional area = 0.5 m²
magnitude of magnetic field =
B = 3 T + (2 T/s)*t.
B = ( 3+ 2 t ) T
induced potential difference = ?
At time = 2 s
we know,
induced emf
∅ = B . A
e = -10 V
magnitude of induced emf
|e| = |-10 V|
e = 10 V
the induced potential difference in the loop = e = 10 V
Is this the answer for the question or is there a question for us?
<span>This is an agrarian society, taken to its extreme. These societies are largely dependent upon farming and related activities as a way of earning income, and also for using the farmed items as a way of supporting oneself as food and clothing.</span>
