Milliampere (mA) is one thousandth of an ampere. Used worldwide for smaller electrical current measurements. Commonly measured by galvanometers and ammeters
Ferromagnetism is the strongest type of material magnetism. Materials with significant magnetic permeability can form permanent magnets. Three other types exist: paramagnetism, diamagnetism, and antiferromagnetism
Ampere (A) is SI unit of electric current, equal to 1 coulomb per second. Named after André-Marie Ampère, considered father of electromagnetism. Established as standard unit at 1881 International Exposition of Electricity
Electric current is the flow of charged particles through conductors. Current is measured in amperes (A) and represented by symbol I. Current can be measured using ammeters or other devices
Electric current is the flow of charge in electric circuits. Current is measured using an ammeter and its SI unit is Ampere. Current can be measured by connecting ammeter in series with load
