Quick Answer
MAGNESIUM FAILURES WITH FERRO RODS occur due to insufficient ferro rod material being ignited, or the ferro rod is not striking the magnesium with sufficient force, leading to incomplete combustion.
Strike Quality and Ferro Rod Material
When striking a ferro rod to ignite magnesium, the quality of the strike is crucial. Aim for a sharp, clean strike with the ferro rod tip, ideally at a 45-degree angle. This will ensure a clean, hot spark that can effectively ignite the magnesium. For best results, use a ferro rod with a high-quality, high-carbon stainless steel tip, as these are more resistant to corrosion and can produce a hotter spark.
Magnesium Rod Angle and Strike Location
The angle and location of the magnesium rod during the strike are also critical. Hold the magnesium rod at a 30-degree angle, with the strike location about 1-2 inches from the top. This allows the ferro rod spark to travel along the length of the magnesium rod, igniting the fuel more efficiently. Additionally, striking the magnesium rod near the top helps to prevent the flame from being extinguished by the molten fuel.
Strike Force and Ferro Rod Size
The strike force and ferro rod size can significantly impact the success of igniting magnesium. Use a ferro rod with a diameter of at least 1/4 inch (6 mm) and a length of about 6-8 inches (15-20 cm). This size rod provides enough mass to generate a hot spark when struck with a decent force. Aim for a strike force that is firm but controlled, as excessive force can break the ferro rod or cause the magnesium to splatter.
