Apparatus for transferring plurality of micro devices and methods of fabrication

A magnetic apparatus, comprising:

• a first structure comprising a first non-magnetic material;
• a second structure comprising a second non-magnetic material on a first portion of the first structure;
• a third structure comprising the second non-magnetic material on a second portion of the first structure;
• a first magnetic structure adjacent to a first sidewall of the second structure;
• a second magnetic structure adjacent to a first sidewall of the third structure;
• a third magnetic structure adjacent to a second sidewall of the second structure, adjacent to a second sidewall of the third structure and extending onto a third portion of the first structure, the third portion between the second sidewall of the second structure and the second sidewall of the third structure;
• and
• a magnet coupled with the first, the second and the third magnetic structures.
