Strength of a magnetic field
1) Increasing or decreasing the number of turns? (of wire)
Increasing
2) Increasing or decreasing current?
Increasing
3) inserting a highly permeable core (increases flux density)
high permeable cores
- Nickel, Iron, Cobalt,
These materials tighten existing flux lines, do not increase # of flux lines
low permeable cores
- air (Pulling out the core)
Review
- Is the North Pole
