Advantages • Adjustable• Scalable to large size• Good field quality
• Small size• Low cost• No power supplies
• Adjustable• Small size• Low cost• Shorter end-fields
Disadvantages • Expensive• Large and heavy
• Not (easily) adjustable
• Unproven design
MagnetsMagnets
• Shown here are copper coils, however for the required field, PC boards would suffice
