Question1:
What is the effect of filling the core of an electromagnet with an iron bar?
filling the core of the solenoid with an iron bar intensifies the magnetic field. In such a case
the magnetic field of the solenoid magnetizes the iron bar, and its field adds to that of the
solenoid. The magnetic field strength of the solenoid will increase.
Question2:
Write three ways to increase the magnetic field of a solenoid.
1- Increase the number of loops.
2- Increase the value of current.
3- Filling the solenoid by a bar magnet.
Question3:
Describe the magnetic field of a solenoid
- The magnetic field inside the solenoid is relatively strong and uniform. Outside the
solenoid the field is weak
- In the ideal case, the magnetic field is uniform inside a solenoid and zero outside.
Question 4:
Sketch the magnetic field of a solenoid.
