Answer:
Current, I = 0.153 A
Explanation:
Given that,
Radius of the circular conducting loop, r = 0.5 m
Resistance of the resistor,
Magnetic field, B = 1 T
Angle with z axis,
Magnetic field increases to 10 T in 4 seconds
To find,
Magnitude of current.
Solve,
According to Faraday's law, the induced emf is given by:
are final flux and the initial flux respectively.
The magnitude of current can be calculated using the Ohm's law as :
I = 0.153 A
Therefore, the magnitude of the current that will be caused to flow in the loop is 0.153 A.
