Answer:
Zero
Explanation:
There's no change in flux as the relative speed is zero . There must be a change in flux to induce emf . ( Faradays Law of Electromagnetic Induction )

Zero emf is induced in the coil.
Explanation:
- When the magnet and a coil are moving along a single line with the same speed then their relative velocity is zero. When the relative velocity is zero then there is no change in flux associated with the coil and hence no emf is induced in the coil.
- An emf voltage gets induced in a coil only when there is a change in magnetic flux with respect to time. This principle is called Faraday's law.
