- description of the numerical problems from Chapter 19 of Physics XII:
Problem 19.1:
This problem typically involves a scenario related to electromagnetic induction. It might ask you to calculate the induced electromotive force (emf) in a coil when there is a change in magnetic flux through it. The formula commonly used is:
\[ \mathcal{E} = -\frac{d\Phi}{dt} \]
where \( \mathcal{E} \) is the induced emf and \( \frac{d\Phi}{dt} \) represents the rate of change of magnetic flux.
Problem 19.5:
This problem often deals with Faraday's law of electromagnetic induction and Lenz's law. It could ask you to determine the direction of the induced current in a loop or coil when there is a change in magnetic flux through it. The key points to consider are:
The direction of the induced emf opposes the change in magnetic flux (Lenz's law).
The magnitude of the induced emf is given by \( \mathcal{E} = -N \frac{d\Phi}{dt} \), where \( N \) is the number of turns in the coil and \( \frac{d\Phi}{dt} \) is the rate of change of magnetic flux.
