Abstract
Fleming's Right-hand Rule (RHR) and ijk-notation are mnemonics that help students identify the direction of magnetic force. Literature has provided successes and limitations of each of these mnemonics, but no literature was found documenting the comparison of these mnemonics used in one Physics concept as these were normally used separately (i.e., RHR for electromagnetism and ijk notation for vectors in Math). This study employed a quasi-experimental one-group posttest-only design and the data were analyzed using Independent Samples t-test. This study underscores that Fleming's Right-hand Rule can better help students in identifying the direction of magnetic force than ijk-notation. The students emphasized that the use of ijk-notation is perplexing particularly when vectors differ in sign conventions, thus the low score using the said mnemonic.
