The EMF induced in coil of the bar magnet with respect to change in flux is calculated as - 1.5 v
Given:
N= 50 turns
change in flux= 0.03 wb/s
emf= - N×[tex]\frac{d}{dt}[/tex]Ф
= - 50×0.03
= - 1.5 v
What is emf in Faraday's law?
Faraday's law describes the magnitude of the voltage (emf), or voltage, induced (generated) during a conductor due to electromagnetic induction (changing magnetic fields). It states that the induced emf during a conducting circuit is proportional to the rate of change of magnetic flux linkage Φ within the circuit.
What is EMF ?
Electromotive force (EMF) is equal to the terminal potential difference when no current flows. EMF and terminal electric potential (V) are both measured in volts, however they're not the same thing. EMF (ϵ) is that the amount of energy (E) provided by the battery to each coulomb of charge (Q) passing through'
