Emf = -N(ΔΦ/Δt) is according to
Correct answer: D. Both B and C
- A. Ampere's Law
- B. Faraday's Law
- C. Lenz's Law
- D. Both B and C
Explanation
Faraday's Law: This law states that an electromotive force (emf) is induced in a closed loop of wire when there is a change in the magnetic flux through the loop over time. The equation "emf = -N(ΔΦ/Δt)" represents this law, where "emf" is the induced electromotive force, "N" is the number of turns in the loop, and "ΔΦ/Δt" is the rate of change of magnetic flux.Lenz's Law: This law is a consequence of Faraday's Law and provides the direction of the induced current in the loop. It states that the direction of the induced current is such that it opposes the change in magnetic flux that caused it. In other words, the induced current creates a magnetic field that counteracts the change in the external magnetic field, trying to maintain the status quo.both Faraday's Law and Lenz's Law are represented by the equation "emf = -N(ΔΦ/Δt)," as it shows the induction of emf due to the change in magnetic flux and the relationship between the induced current and the change in magnetic field.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
