Electric Force, Field, and Potential

Inject dyed streams into fluid flow adjacent to solid boundaries under laminar conditions, then analyze velocity gradients via high-speed imaging.

Measure pressure differences across several points assuming direct correlation with velocity magnitude disregarding vector directionality.

Employ pitot tubes randomly throughout fluid flow disregarding boundary layer effects or define strict laminar conditions.

Compute velocities using Bernoulli’s equation alone under turbulent conditions inherently unsuitable due interpretation challenges posed by complex flows near boundaries.

Implement sensors capable of detecting minute changes in magnetic flux density instead of relying solely on visual observations of compass needles.

Use larger magnets so that compass needle deflections are more pronounced and easier to observe visually.

Replace traditional compasses with digital ones without compensating for electronic interference or calibration errors introduced by such instruments.

Record observations from greater distances to minimize disturbances caused by nearby ferromagnetic materials other than your test magnets.

A circular path centered on the wire as magnetic forces do no work on charges moving perpendicular to their velocity.

A radial path away from the wire because there would be no component of force along this path.

An elliptical orbit around the wire since variable distance implies changing magnetic flux and induced emf.

Any straight-line path parallel to the wire due to constant magnetic field strength along such paths.

Rely on predetermined theoretical values for gravitational acceleration $g = 9.81 , \mathrm{m/s^2}$ across all points of measurement.

Calculate potential energies using varying heights along the plane without measuring local gravitational changes directly.

Employ sensitive gravimeters at multiple points along the plane while accounting for known mass distributions around it.

Use typical spring scales to weigh objects at different locations ignoring local mass distribution anomalies entirely.

Ignore air resistance as it has minimal impact on scalar fields like gravitational potential energy.

Conduct experiments in a vacuum chamber to eliminate air resistance entirely.

Calculate an average value for air resistance based on object size and shape and adjust measurements accordingly.

Only use heavy objects where air resistance is negligible compared to their weight.
