Considering the following statements, mark only those that are correct. I- The presence of a magnetic field is a sufficient condition for an induced current to arise in a conductor. II- The original induced current generates a magnetic field. III- When a field appears in the primary of a transformer, a current arises in the secondary with the same direction as the magnetic field. IV- A material with high remanence coefficient has a low coercive force.
