Faraday’s Law ApplicationsThe Magnetic Team: - Catherine Perez- Giovanni Bonilla- Dunie Navarro
Michael Faraday Born September 22, 1791 English chemist and
physicist Studied the magnetic field
around a conductor carrying a DC electric current
Established the basis for the electromagnetic field concept in physics
His inventions of electromagnetic rotary devices formed the foundation of electric motor technology
Making electricity become viable for use in technology
Faraday’s Law of Induction
Faraday’s Law states that the electromotive force is directly proportional to the time rate of change of the magnetic flux through a loop:
Є = - dФB/dt where ФB = ∫ B. dA
Magnetic Flux
Magnetic Flux is a measure of quantity of magnetism, taking into account the strength and extent of a magnetic field:
ФB = ∫ B. da ФB = BAcosθ

Electric Motor
An electric motor is a motor that uses electrical energy to produce mechanical energy, usually through the interaction of magnetic fields and current-carrying conductors.
Electric Motor as Electric Generator
A DC motor can be used as a DC generator. Using mechanical energy to rotate the coil inside the motor at uniform angular velocity in a magnetic field, it will produce an electromotive force which is measured in Volts
Due to this resulting voltage, the light bulb emits light and the fan rotates
