Lesson 6 strength and magnetic forces quick check answers

Answer 1

1. What determines the strength of a magnetic force between two objects?
- The strength of a magnetic force between two objects is determined by the magnetic field strength and the distance between the objects.

2. True or False: The strength of an electromagnet depends on the number of coils in the wire.
- True

3. What factors determine the strength of a magnetic force between two magnets?
- The strength of a magnetic force between two magnets is determined by the magnetic field strength, the distance between the magnets, and the orientation of the magnets.

4. How does increasing the distance between two magnets affect the strength of the magnetic force?
- Increasing the distance between two magnets decreases the strength of the magnetic force between them.

5. What is the unit of measurement for magnetic field strength?
- The unit of measurement for magnetic field strength is tesla (T).
