Question

The total force tending to set up a magnetic flux in a magnetic circuit is the

magnetizing force. It is usually designated by the letter H, and the unit is the

Oersted - A magnetizing force of 8000 A/m is applied to a circular magnetic

circuit of mean diameter 30 cm by passing a current through a coil wound on

the circuit. If the coil is uniformly wound around the circuit and has 750 turns,

what is the current in the coil? ​

Answer 1

The oersted (symbol Oe) is the unit of the auxiliary magnetic field H in the centimetre–gram–second system of units (CGS).[1] It is equivalent to 1 dyne per maxwell.
