The component of the external magnetic field along the central axis of a turn circular coil of radius cm decreases from t to t in s. if the resistance of the coil is ω, what is the magnitude of the induced current in the coil?

  I =  Δ(N*B*A) / R*Δt

                   and

               I= ΔФ / R*Δt

Explanation:

what is electromagnetic induction?

electromagnetic induction is a mechanism where current is induced in a coil or loop. To be specific Faraday's law of electromagnetic induction says that induced EMF is proportional to the induced current or emf.

FORMULA

I= ΔФ / R*Δt

BY EXPANDING THE FORMULA WE GET

ΔФ= Δ(N*B*A)  

by putting the value in equation we get:

I =  Δ(N*B*A) / R*Δt

where A is area of circular coil π*r²

DATA

N is number of turns in the coil

r  is radius of the circular coil

ΔB is  magnetic field

Δt is time

R is resistance of coil

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
