SUMMARY
The discussion centers on calculating the electromotive force (EMF) induced in a disk with an area of 0.003 m² subjected to a magnetic field (B) increasing at a rate of 0.02 T/s. Using Faraday's law of induction, the magnetic flux (φ) is calculated as φ = B × A, yielding a value of 0.00006 Wb. The EMF (E) is then determined using the formula E = -N(φ)/t, resulting in an EMF of -0.00006 V, with the unit of EMF confirmed as Volts.
