Question

The mutual inductance of two coaxial coils is 2H. The current in one
coil is changed uniformly from zero to 0.5A in 100 ms. Find the :
(i) change in magnetic flux through the other coil. ?
(ii) emf induced in the other coil during the change, a .​

Answer 1

Answer:

Explanation:tttttffffffffffffffffdddddddd

Answer 2

(i) Change in magnetic flux will be 1 weber

(ii) emf induced will be equal to 10 volt

Explanation:

We have given mutual inductance of two coaxial coil is 2H

Current is changes from 0 to 0.5 A

So change in current di = 0.5-0 = 0.5 A

Change in time dt = 100 ms = 0.1 sec

(ii) Emf induced in second coil will be equal to $e=M\frac{di}{dt}=2\times \frac{0.5}{0.1}=10volt$

So emf induc$\frac{d\Phi }{0.1}=10$ed will be equal to 10 volt

(ii) According to Faraday law $N\frac{d\Phi }{dt}=e$

$\frac{d\Phi }{0.1}=10$

$d\Phi =1weber$

Change in magnetic flux will be equal to 1 weber
