Abstract
An apparatus may determine the quality of a fencing blade. The apparatus may include an electrical current source; a fencing blade to be tested for quality; two electrical cables, each connected between the electrical current source and the fencing blade so as to cause current from the current source to travel through at least a portion of the fencing blade; and a magnetic field sensor in sufficient proximity to the fencing blade so as to enable the magnetic field sensor to detect a magnetic field generated by the fencing blade when the current passes through the fencing blade.

An apparatus for determining the quality of a fencing blade comprising:
- an electrical current source;
- a fencing blade to be tested for quality;
- two electrical cables, each connected between the electrical current source and the fencing blade so as to cause current from the current source to travel through at least a portion of the fencing blade;
- and
- a magnetic field sensor in sufficient proximity to the fencing blade so as to enable the magnetic field sensor to detect a magnetic field generated by the fencing blade when the current passes through the fencing blade,
- wherein the electrical current source is configured to generate current at multiple different selectable levels, and
- wherein the magnetic field sensor is part of a mobile phone, and the magnetic field sensor is configured to measure both magnetic field intensity and direction of the fencing blade before current travels through the fencing blade and while current travels through the fencing blade at each of the multiple different selectable levels.
A process for determining the quality of a fencing blade comprising:
- electrically and detachably connecting an electrical current source to the fencing blade so as to cause current from the current source to travel through at least a portion of the fencing blade;
- placing a magnetic field sensor in sufficient proximity to the fencing blade so as to enable the magnetic field sensor to detect a magnetic field generated by the fencing blade when the current passes through the fencing blade, wherein the magnetic field sensor is part of a mobile phone;
- measuring magnetic field intensity and direction of the fencing blade before current travels through the fencing blade;
- activating the electrical current source to cause current from the current source to travel through at least a portion of the fending blade;
- causing current at different levels to travel through the at least portion of the fencing blade;
- measuring the magnetic field produced by the fencing blade with the magnetic field sensor while current is travelling through the fencing blade at each of the different levels;
- and
- determining the quality of the fencing blade based on all of the measured magnetic fields.
