Acontinuous length of wire is made into 10 coaxial loops, located in the plane of this page. each loop has a cross sectional area of 0.5 m2. a uniform time-varying magnetic field is directed into the page and its magnitude is given by b = 3t + (2t/s)*t. what is the induced potential difference in the loop and the direction of the induced current at t = 2.0 s?

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

it has to be b, about 97 percent.

it would be c. predictability
