Which of the following statements is not correct for electromagnetic induction? |
The magnitude of induced emf in a circuit is equal to the time rate of change of magnetic flux through the circuit. The magnitude of induced emf in a circuit is equal to the total change of magnetic flux through the circuit. The induced emf can be increased by increasing the number of turns N of a closed coil. The polarity of induced emf is such that it tends to produce a current which opposes the change in magnetic flux that produced it |
The magnitude of induced emf in a circuit is equal to the total change of magnetic flux through the circuit. |
The correct answer is Option (2) → The magnitude of induced emf in a circuit is equal to the total change of magnetic flux through the circuit. |
