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

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
