Frequently Asked Questions
-
What does the oersted measure?
-
Oersted measures magnetic field strength, also called magnetizing force, in the cgs electromagnetic unit system.
-
How is ampere per centimeter used?
-
Ampere per centimeter quantifies linear current density along a conductor, useful in describing current distribution on electrodes and PCB traces.
-
Can I directly convert oersted to ampere per centimeter?
-
Yes, using the conversion factor 1 Oe = 0.7957747151 A/cm, but interpret results carefully due to differences in what the units physically represent.
-
Why convert from oersted to ampere per centimeter?
-
Converting helps translate older magnetic field data into modern linear current density terms relevant for electrical and electrochemical engineering.
