A circular loop is rotated 360° in a magnetic field. Which of the following is true for the induced current produced in the coil?
only the magnitude of the current changes
only the direction of the current changes
both the magnitude and the direction of the current change
the amplitude of the current changes
both magnitude and direction change.
Both the magnitude and the direction of the current change.
To determine what happens to the induced current in a circular loop that is rotated 360° in a magnetic field, we need to understand Faraday's law of electromagnetic induction.
According to Faraday's law, the magnitude of the induced electromotive force (EMF) is directly proportional to the rate of change of the magnetic field passing through the loop. In this case, as the loop is rotated 360°, the magnetic field passing through the loop remains constant since the loop remains in the same field. Therefore, there is no change in the magnetic field, and as a result, no current is induced.
So, none of the given options is true for the induced current produced in the coil when it is rotated 360° in a magnetic field.
