Draw on a piece of paper the uniform magnetic field directed out of a page, it means towards you. Magnetic field is uniform in space and decreasing in magnitude. Induced electric field as viewed from above is directed:

A. Counterclockwise
B Clockwise
C. Is zero because there is no conducting loop present
D. Electric field is always from positive charge to negative

Answer:

A. Counterclockwise

Explanation:

Electric fields can be created in vacuum space by variable magnetic fields. If we focus in the Lenz's law we have

[tex]\int Edl=-\frac{d\Phi_{B}}{dt}[/tex]

and by taking into account the right hand rule we deduce the direction of the circulation of the field

I hope this is useful for you
