Questions from David Sang and Darrell Hamilton Solutions for Chapter: Magnetism, Exercise 3: Exercise 16.3 with Hints & Solutions
State why an electromagnet is useful?
Explain whether you would use soft iron or steel for an electromagnet.
Describe a method by which you could determine the polarity of an electromagnet.
A woman was doing some work on her house. She was using a power drill to make a hole in a steel sheet. A stray piece of metal flew off the drill and hit her in the eye. When she went to hospital, the doctor used a very strong magnet to remove the metal. State whether a permanent magnet or an electromagnet would me most suitable to remove the metal. Explain your answer.
Describe a method by which you could directly measure the strength of an electromagnet's field by measuring the force produced by it and compare the strengths of different electromagnets. You should note the factors that affect the strength of the field and how you would vary them?
