Answer:
The magnitude of the current is 5.45 mA.
Explanation:
Given that,
Resistance = 10.0 ohm
Radius = 0.10 m
Magnetic field = 1.0 T
Angle = 30°
Increase magnetic field = 7.0 T
Time t = 3.0 s
Number of turns = 1
We need to calculate the initial flux
Using formula of flux
Put the value into the formula
We need to calculate the final flux
We need to calculate the induced emf
Using formula of emf
Put the value into the formula
We need to calculate the current
Using formula of current
Put the value into the formula
Hence, The magnitude of the current is 5.45 mA.
