Suppose you are looking into one end of a long cylindrical tube in which there is a uniform electric field, pointing away from you.If the magnitude of the field is decreasing with time the direction of the induced magnetic field is:

According to Faraday's law of induction, a changing magnetic field induces an electric field, and a changing electric field induces a magnetic field. In this case, the decreasing electric field is changing with time, so it will induce a magnetic field. The direction of the induced magnetic field can be determined using Lenz's law, which states that the induced magnetic field opposes the direction of the change in the electric field that caused it. Since the electric field is decreasing away from you, the induced magnetic field will be in the direction that opposes this change, which is in the clockwise direction when viewed from your end of the tube.
