Question

Oersted is the unit of
A. Intensity of magnetization
B. Magnetic Moment
C. Magnetic Induction
D. Magnetic Flux

Answer 1

Hint: The given unit is a unit from the C.G.S system.

Complete step by step answer:
The oersted is the unit of magnetic induction the C.G.S scale. It is equivalent to 1 dyne per Maxwell, where dyne is the unit of force and Maxwell is the unit of magnetic flux in C.G.S scale. The unit was put forward to honour the contribution of Hans Christian Oersted who was a Dutch physicist who discovered the connection between magnetism and electric current when a magnetic field produced by a current-carrying copper bar deflected a magnetised needle.
So the answer to the question is option (C)- Magnetic Induction.
Additional Information:
The C.G.S unit for force is dyne (Dyn).
The C.G.S unit for pressure is barye (Ba).
The C.G.S unit for velocity is centimetre per second (cm/s).
The C.G.S unit for acceleration is gal (Gal).
The C.G.S unit for mass is gram (g).
The C.G.S unit for wavenumber is kayser (K).
The stored energy in a magnet, called magnet performance or maximum energy product, is typically measured in units of megagauss-oersteds (MG⋅Oe).

Note: Tesla is the SI unit for magnetic induction.
The oersted is closely related to the gauss, the CGS unit of magnetic flux density. In a vacuum, if the magnetizing field strength is 1 Oe, then the magnetic field density is 1 G.
Gauss is the unit of magnetic flux density and the oersted is the unit of magnetic field strength. The gauss is defined through a time-dependent change in magnetic flux density and the oersted is defined through the field created by an electric current.
