1. How does a solenoid behave like a magnet? Can you determine the north and south poles of a current–carrying solenoid with the help of a bar magnet? Explain.
A coil of many circular turns of insulated copper wire covered closely in the shape of a is called a solenoid. One end of the solenoid acts as a , while the other end acts as the . The magnetic field lines inside the solenoid are in the form of .
By taking a bar-magnet with known north poles near one end of the solenoid and showing repulsion, that end of the solenoid is the , and the other end is the . The property of magnet le. like poles and unlike poles is used for the determination of poles of the solenoid.
2. Imagine that you are sitting in a chamber with your back to one wall. An electron beam, moving horizontally from back wall towards the front wall, is deflected by a strong magnetic field to your right side. What is the direction of magnetic field?
Explanation:
The electron beam travels in a straight line, and the magnetic field is coming from the right side. The beam travelling in a straight line will be deflected by the strong magnetic field coming from the right side.
The direction of the electron beam is in a straight line from the back wall towards the front wall. We know that the current direction will be in the of the flow of electrons. Therefore, the current direction will be in a. Since the electron beam has deflected to your right side, the direction of force is towards.
The direction of the magnetic field, force and current can be determined by the.
Hence, according to , the thumb represents the and the middle finger represents the , then the will be given by the direction of the forefinger and it will be in a direction.
