Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following factors does NOT affect the strength of an electromagnet?
Number of turns in the coil
Amount of current flowing through the coil
Type of material used for the core
Direction of current flow
2. An electromagnet is a type of magnet in which the magnetic field is produced by an electric .
3. The core of an electromagnet is typically made of a material, such as iron, to enhance its magnetic properties.
4. Describe the main difference between a permanent magnet and an electromagnet.
5. State two practical applications of electromagnets in everyday life.
6. Observe the electromagnet diagram below and answer the questions that follow.
a) Indicate the direction of the magnetic field lines around the core.
b) If the number of turns in the coil were doubled, how would this affect the strength of the electromagnet?
7. Reversing the direction of current flow in an electromagnet will reverse the polarity of its magnetic field.
