Rowland's ring (aka Rowland ring) is an experimental arrangement for the measurement of the hysteresis curve of a sample of magnetic material. It was developed by Henry Augustus Rowland. The geometry of a Rowland's ring is usually a toroid of magnetic material around which is closely wound a magnetization coil consisting of a large number of windings to magnetize the material, and a sampling coil consisting of a smaller number of windings to sample the induced magnetic flux. The electric current flowing in the magnetization coil dictates the magnetic field intensity in the material. The sampling coil produces a voltage proportional to the rate of change of the magnetic field in the material. By measuring the time integral of the voltage in the sampling coil versus the current in the magn

  • El Anillo de Rowland es una herramienta utilizada para el estudio de la magnetización de un material ferromagnético, como el hierro, para deducir su comportamiento. Fue desarrollado por el físico estadounidense Henry Augustus Rowland. El anillo tiene un aspecto de un delgado toroide de sección circular a cuyo alrededor está envuelta una bobina primaria; la bobina recibe la corriente Ip produciendo un campo magnético cuya intensidad está determinada por la capacidad de magnetización del núcleo, será mayor si el núcleo es en material ferromagnetico. La ecuación del campo magnético dentro del espacio toroidale es: B=B0+BM donde B es el campo electromagnético, B0=μ0nIp intensidad campo magnético en ausencia de núcleo en material ferromagnetico, y BM es el contributo del núcleo en material ferromagnético. * Portal:Física.

  • Rowland's ring (aka Rowland ring) is an experimental arrangement for the measurement of the hysteresis curve of a sample of magnetic material. It was developed by Henry Augustus Rowland. The geometry of a Rowland's ring is usually a toroid of magnetic material around which is closely wound a magnetization coil consisting of a large number of windings to magnetize the material, and a sampling coil consisting of a smaller number of windings to sample the induced magnetic flux. The electric current flowing in the magnetization coil dictates the magnetic field intensity in the material. The sampling coil produces a voltage proportional to the rate of change of the magnetic field in the material. By measuring the time integral of the voltage in the sampling coil versus the current in the magnetization coil, one obtains the hysteresis curve. (en)
  • L'Anello di Rowland è uno strumento utilizzato per studiare la magnetizzazione di un materiale ferromagnetico, come il ferro, per capirne il comportamento. Fu sviluppato dal fisico statunitense Henry Augustus Rowland. L'anello ha la forma di un sottile toroide di sezione circolare al cui intorno è avvolta una bobina primaria; una corrente Ip è inviata nella bobina primaria generando un campo magnetico la cui intensità è determinata dalla capacità di magnetizzazione del nucleo, maggiore se il nucleo è in materiale ferromagnetico. L'equazione del campo magnetico all'interno dello spazio toroidale è B=B0+BM dove B è il campo elettromagnetico, B0=μ0nIp intensità campo magnetico in assenza di nucleo in materiale ferromagnetico, e BM è il contributo del nucleo in materiale ferromagnetico.
