Solution

  1. A negative emf can be possible. As, negative emf causes a current to flow, which produces a magnetic field that opposes the change in magnetic flux.
  2. Suppose the emf is induced by a magnetic field increases in the -z direction, the emf will be induced to produce a magnetic field in the +z direction.
  3. Therefore, we can have negative emf.
