How should a closed conducting loop move in a uniform magnetic field that does not depend on time: translationally or rotationally, so that an induction current appears in it?
For induction current to occur, the circuit must rotate in a magnetic field. In this case, the magnetic flux through the surface bounded by the circuit changes with time from zero to the maximum value, and this change in the magnetic flux causes the appearance of an induction current in the circuit.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
