Question

Formula for rate of change of magnetic field

Answer 1

Magnetic flux F is defined by F=BA where B is the magnetic field or averagemagnetic field and A is the area perpendicular to the magnetic field. Note that for a given rate of change of the flux through the coil, the voltage generated is proportional to the number of turns N which the flux penetrates.
hope this answer is useful to u if helps plz mark it as brain list

Answer 2

Explanation:

Hyperphysics Magnetic flux F is defined by F=BA where B is the magnetic field or average magnetic field and A is the area perpendicular to the magnetic field.

• Note that for a given rate of change of the flux through the coil, the voltage generated is proportional to the number of turns N which the flux penetrates.
