Asingle-turn plane loop of wire with a cross-sectional area 200 cm2 is perpendicular to a magnetic field that increases uniformly from 0.200 t to 2.800 t in 2.20 seconds. what is the magnitude of the induced current if the resistance of the coil is 8.00 ω?

Induced current,                                        

Explanation:

Given that,

Area of cross section of the wire,

Time, t = 2.2 s

Initial magnetic field,

Final magnetic field,

Resistance of the coil, R = 8 ohms

The expression for the induced emf is given by :

= magnetic flux

So, the induced emf in the loop is 0.023 volts. The induced current can be calculated using Ohm's law as :

So, the magnitude of the induced current in the loop of wire is . Hence, this is the required solution.

it is the second option.
