Discussed herein are methods of orienting one-dimensional and two-dimensional materials via the application of stationary and rotating magnetic fields. The oriented one-dimensional and two-dimensional materials may exhibit macroscopic properties, and may be employed in various measurement devices as well as thermal and electrical shielding applications or battery devices. A single 1D or 2D material may be suspended in another material such as dionized water, polymer(s), or other materials during the orientation, and the suspension may remain as a liquid or may be solidified or partially solidified to secure the oriented material(s) into place. The 1D and 2D materials that respond to the magnetic orientation may further cause other elements of the suspension to be oriented in a similar manner.
