An electric field
The direction of induced magnetic field if electric field away from you and increasing.
The direction of induced magnetic field if the direction of electric field is towards you and decreasing.
Answer to Problem 1Q
The direction of magnetic field will be clockwise for both the cases.
Explanation of Solution
Write the expression for displacement current as.
Here,
From the above expression it is clear that displacement current is proportional to rate of change of electric flux.
The electric flux is directed away from the observer and is increasing so the direction of displacement current is also away from the observer and therefore the magnetic field will be in clockwise direction.
The electric field is toward the observer and is decreasing so
Conclusion:
Thus, the direction of magnetic field will be clockwise for both the cases.
