Study Notes
Question 28
- If the cross-sectional area of a magnetic field increases, the flux remains the same, but the flux density changes
- The flux density will decrease
Question 29
- When the current through a coil of an electromagnet reverses, the direction of the magnetic field reverses.
Question 30
- The ability of a material to remain magnetized after removal of the magnetizing force is called retentivity.
