Reactive Effect
Ferro-magnetic and electrically conductive materials produce reactive effects. Iron is
both electrically conductive and ferro-magnetic. The effect for small iron particles is
ferro-magnetic, which is largely opposite that of a metal such as copper. Copper is a
strong electrical conductor.
Dry Products
Dry products produce very little, or zero product effect. Examples of dry products are
some tablets, cookies, candy, chocolate, dry powders, oil-based products such as peanut
butter, and cereals.
Wet Products
Wet products produce a larger product effect. Examples of wet products are bread,
buns, cakes, meat, and dairy products.
Metal Film Products
Products packaged using metallic wrappers usually require a low search-head frequency
such as 50 kHz.
