Question

What will happen if there is a change in a magnetic field?

A)The magnetic field will increase.
B)The magnetic field will decrease.
C)An electric field will be produced.
D)The magnetic field will collapse.

Answer 1

an electric field will be produced (in probably wrong)

Answer 2

C)An electric field will be produced.

Step-by-step explanation:

When magnetic field changes with time then it will induce electric field in a closed loop.

This is also known as non conservative electric field which is given by the equation

`\int E.dl = -A.(dB)/(dt)`

for closed loop of radius "r" we have

`E.(2\pi r) = -A(dB)/(dt)`

`E = - (A)/(2\pi r)(dB)/(dt)`

so here the correct answer will be given as

C)An electric field will be produced.
