Asingle loop of wire with an area of 0.0900 m2 is in a uniform magnetic field that has an initial value of 3.80 t, is perpendicular to the plane of the loop, and is decreasing at a constant rate of 0.190 t s. (a) what emf is induced in this loop? (b) if the loop has a resistance of find the current induced in the loop

(a) 0.0171 V

Explanation:

A = 0.09 m^2, dB/dt = 0.190 T/s

(a) According to the law of electromagntic induction

e = dФ / dt

e = A dB / dt

e = 0.09 x 0.190 = 0.0171 V

(b)

as we know

i = e / R

we can find induced current by dividing induced emf by resistance

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
