When an electrically-conducting structure is exposed to a time-varying magnetic field, an electrical potential difference is induced across the structure. … Faraday's Law describes the generation of electric potential by a time-varying magnetic flux. This is a form of electromagnetic induction.Mar 21, 2021

What is mean by time varying magnetic field?
Time varying magnetic field →B(t) or any quantity. It means which varies with time. It means that, f(t) is different from a time t2 which is either before or after t1, if t1 and t2 are distinct.
What is a varying magnetic field?
Varying Magnetic Field: Each point on a surface is associated with a direction, called the surface normal; the magnetic flux through a point is then the component of the magnetic field along this normal direction.
What are time varying currents?
A time varying current (or alternating current) is a current whose magnitude is a function of time. The most common is a sinusoid, i = I sin(wt). It can be generated several different ways.
What is time varying electric field?
When an electrically-conducting structure is exposed to a time-varying magnetic field, an electrical potential difference is induced across the structure. … Faraday's Law describes the generation of electric potential by a time-varying magnetic flux. This is a form of electromagnetic induction.
What does a time varying electric field yield?
Answer: Time varying magnetic field produces electric field. … it produce electric field (induced emf) in conductor.
What time varying current the field or waves will be?
electromagnetic But for time varying currents, the field or waves will be electromagnetic. Explanation: The force in any closed circuit due to the change in the flux linkage of the circuit is called as electromotive force EMF. This phenomenon is called as Faraday's law.
