The small solenoid shown below on the left is inserted into a larger solenoid (on the right). The smaller solenoid is connected to an ammeter while the larger solenoid is connected to a battery. The current is turned on once the smaller solenoid is completely inside the larger solenoid. What is observed on the ammeter?
|
The ammeter will have a reading as long as the power is turned on to the larger solenoid, since current is induced in the smaller solenoid by the magnetic field of the larger solenoid. |
||
|
The ammeter will not have a reading, because the axis of the smaller solenoid is in the same direction as the axis of the larger solenoid. |
||
|
The ammeter will have a reading as the power is turned on, but the reading will quickly drop to zero again. |
||
|
The ammeter will not have a reading, because the smaller solenoid is not connected to a power supply. |
