Magnesium anodes are known to?

• A. Deliver lower currents
• B. Deliver a higher current
• C. Corrode faster than others
• D. Require more maintenance

Answer: (B)

Magnesium anodes are known to deliver a higher current, making them effective for cathodic protection systems, particularly in environments where they are used in fresh or low conductivity waters. This property is due to magnesium's higher electrochemical potential compared to other anode materials like zinc and aluminum. Consequently, when magnesium anodes corrode, they produce a more substantial flow of electrons, which is essential for providing adequate cathodic protection to metal surfaces. This higher current output is beneficial because it allows for better protection of the structure being safeguarded, effectively slowing down the rate of corrosion. In many applications, especially in soils with high resistivity or where the protective requirements are higher, magnesium anodes are often preferred due to their ability to provide a more aggressive level of cathodic protection.
