Question

An unmarked magnet is brought near the right end of a solenoid, there is a positive current observed in the ammeter, meaning that the conventional charge flow is directed into the positive terminal of the ammeter. What is the polarity of the end of the magnet that was inserted into the solenoid? Explain. An unmarked magnet is brought near the right end of a solenoid, there is a positive current observed in the ammeter, meaning that the conventional charge flow is directed into the positive terminal of the ammeter. What is the polarity of the end of the magnet that was inserted into the solenoid? Explain.

Explanation / Answer

As the current in the ammeter is to the right, so, the current is clockwise on the right end of the solenoid. Now, by Right hand thumb rule, applied magnetic field must be directed towards right on the right end.bso, the polarity of the magnet is south pole on the left side and north on the right side.
