As an externally generated magnetic field through a certain conducting loop increases in magnitude, the field produced at the points inside the loop by the current induced in the loop
As an externally generated magnetic field through a certain conducting loop increases in magnitude, the field produced at the points inside the loop by the current induced in the loop
The correct option is D must be opposite to applied field
Step 1: Given data
Externally generated magnetic field through a certain conducting loop increases in magnitude.
Step 2: Explanation of the correct options
According to Lenz's law, induced emf in the circuit generates a magnetic field that opposes the change of the field. Induced emf tries to maintain the original flux associated with the circuit. Therefore the current may be increased or decreased in magnitude.
Hence, options A, C, and D are correct.
Step 3: Explanation for the incorrect option
As it is not necessary to always have an increase in the current.
Hence option B is incorrect.
