Question 1

What is the difference between A/m and oersted?

Accepted Answer

A/m is the SI unit, oersted (Oe) is the CGS unit. 1 Oe ≈ 79.577 A/m.

Question 2

What is magnetic field strength?

Accepted Answer

Magnetic field strength (H) measures the magnetizing force. It relates to flux density (B) through B = μH, where μ is permeability.

Question 3

What is the difference between B (flux density) and H (field strength)?

Accepted Answer

H is the externally applied magnetizing field, while B is the total magnetic flux density including the material's response. In vacuum, B = μ₀H. In magnetic materials, B = μ₀(H + M), where M is the magnetization.
