Due to skin effect, the magnetic field is limited by the thickness of the coin, the size and excitation frequency, and the coin surface coating material permeability and resistivity are related

Due to skin effect, the magnetic field through the limited thickness of the coin, its size and excitation frequency, the coins are magnetic permeability and resistivity of coatings and materials relevant

As a result of the skin effect, magnetic field penetration coin thickness is limited, its size and the excitation frequency, coin surface coating and the material quality magnetic conductivity and the electronic resistivity all concern

In effect, the magnetic field through coins tend skin thickness, which has a limited size of the incentive and frequency, coins surface coating and materials of the magnetic and resistivity are the actual rates

Due to skin effect, the magnetic field through the limited thickness of the coin, its size and excitation frequency, the coins are magnetic permeability and resistivity of coatings and materials relevant
