Age 15Explain it to a 15-year-oldConnect it to the formula

Electrophoretic mobility is signed or magnitude migration velocity divided by applied electric-field magnitude. This page isolates applied electric-field magnitude and verifies it in the original relationship. The rule is b=a/c. Its input values are electrophoretic mobility, measured migration velocity, and the main result is applied electric-field magnitude. For example: measured migration velocity=0.0024 and applied electric-field magnitude=240 produce electrophoretic mobility=0.000009999999999999999.
