This study investigates a Varian magnet composed of ferrous material with a 0.030” air gap. The focus is on the properties of the magnet, specifically the estimated clamp force per unit, which is approximately 35 pounds. Additionally, measurements of leakage flux are detailed, revealing values below 0.005 Tesla (5 Gauss) above the pole surface and below 0.015 Tesla (15 Gauss) one inch away from the unit. Understanding these characteristics is crucial for the optimization of magnetic applications in varied settings.
