Coercivity, measured in Oersteds (Oe.), is very loosely defined as the magnetic field required to encode or erase a magnetic stripe. Ordinary low coercivity magnetic stripes (often called loco) are rated at 300 Oersteds; some others are in the range of 600-650 Oe. High coercivity stripes (often called hico or high energy) are generally in the range of 1250-4000 Oe. Bank and financial stripes average around 2750 Oe. High coercivity tapes are more resistant to accidental erasure.
measure of how permanent a magnet is; permanent magnets have a high coercivity. The intensity of a magnetic field needed to demagnetize a substance.
Characteristic of a magnetic stripe indicating the power of the magnetic field required to encode the card. Cards are available in low and high coercivity versions.
adj. the measure (usually expressed in Oersteds) of a magnetic material's resistance to being recorded or erased. Magnetic stripe cards are either low coercivity or high coercivity.
(Hc) Coercivity is a measure of the magnetic field that is needed to reduce magnetization in a thin-film layer to zero. A material's coercivity corresponds to its magnetic strength. The measure for coercivity is an Oersted (Oe). See also Remnant magnetization.
Demagnetization force required to reduce polarization or induction to zero.
A technical term used to designate how strong a magnetic field must be to affect data encoded on a magnetic stripe. Coercivity is measured in Oersteds (Oe). Coercivity is the measure of how difficult it is to encode information in a magnetic stripe.
The intensity of the magnetic field needed to reduce the magnetization of a ferromagnetic material to zero after it has reached saturation.
The level of demagnetizing force that would need to be applied to a tape or magnetic particle to reduce the remanent magnetization to zero. A demagnetizing field of a level in excess of the coercivity must be applied to a magnetic particle in order to coerce it to change the direction of its magnetization. Coercivity is the property of a tape that indicates its resistance to demagnetization and determines the maximum signal frequency that can be recorded by a tape. Hc is the common abbreviation for coercivity.
The strength of the magnetic field required to reverse the polarity of bits
Value of the opposing magnetic intensity that must be applied to a material to remove the residual magnetism when it has been magnetized to saturation.
The amount of applied magnetic field (of opposite polarity) required to reduce magnetic induction to zero. It is often used to represent the ease with which magnetic media can be degaussed.
The amount of power needed to magnetize or demagnetize a permanent magnet. Measured in MegaGauss Oersted (mGO)
The property of a magnetic material, as on a magnetic stripe keys, which is a measure of the coercive force. It is used when describing the strength of magnetic saturation when discussing magnetic stripe card keys.
Coercivity is the method used to encode a magnetic stripe. There are both high and low coercivity. High coercivity is a long-term solution for encoding cards (credit cards). Low coercivity is for short-term encoding of gift cards, hotel keys, IDs. High coercivity is black and low is brown.
the field strength required to change the magnetic state of magnetic material; expressed in Oersteds
A measure of the strength of a magnetic field. Fields are expressed as low or high by the terms LoCo and HiCo.
In materials science, the coercivity, also called the coercive field, of a ferromagnetic material is the intensity of the applied magnetic field required to reduce the magnetization of that material to zero after the magnetization of the sample has been driven to saturation. Coercivity is usually measured in oersted or ampere/meter units and is denoted HC.
