Practical worksheet
Q. No 1: List three sources of magnetic fields.
 
 
 
 
Q. No 2: What is the difference between a permanent magnet and an electromagnet?
 
 
 
 
Q. No 3: What are the different types of artificial magnets?
 
 
 
 
Q. No 4: 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. 
 
 
 
 
 
Q. No 5: What is the difference between magnet and solenoid?
 
 
 
 
 
 
Discussion:
1. The more turns of wire your magnet has, the better. Keep in mind that the further the wire is from the core, the less effective it will be.
The more current that passes through the wire, the better. Caution! Too much current can be dangerous!  Why?
 
 
 
2. Why is it (in detail) that the more coils you add to an electromagnet, the stronger its magnetic field is?
 
 
 
3. Try experimenting with different cores. Explain.  
 
 
 
4. Student can test  core with a permanent magnet.  Explain.
