When the current through a solenoid increases at a constant rate the induced current?
Answers
When the current through a solenoid increases at a constant rate, the induced current also increase with time but in the opposite direction of the inducing current.
Solenoid is coil of wire used as electromagnet, whose purpose is to generate a controlled magnetic filed, it works on the Faraday's law of electromagnetic induction.
When we increase the current through a solenoid, the eddy current throughout the solenoid also increases, which induced a current in the opposite direction, as the amount of current increase, the rating of induced current will also increase in the same proportion.
Therefore, When the current through a solenoid increases at a constant rate, the induced current also increase with time but in the opposite direction of the inducing current.
Answer:
Explanation:
When the current through a solenoid increases at a constant rate the induced current:-
1. Is constant and is in the direction of the inducing current.
2. Is constant and is opposite to the direction of the inducing current.
3. Increase with time and is in the direction of the induced current.
4. Increase with time and opposite to the direction of the inducing current.
