What is a magnetic bar?

Magnetic bar changes in deposition amount due to different magnet bar shapes

The shape with the least amount of sediment is triangular. Next is the square shape and then the round shape. Triangular shapes are most suitable for applications that prevent powder from accumulating.

Internal Structure

Inside the magnet bar, multiple magnets are built in such a way that similar poles repel each other.

Manufacturable size

Manufacturable sizes and machined screw hole diameters vary depending on the exterior diameter.
