Misinterpreting Right-Hand Rule Application:
Misinterpretation of the right-hand rule occurs when users apply the rule incorrectly. The rule states that if you point your thumb in the direction of current flow (or conventional current), your fingers curl in the direction of the magnetic field. This incorrect usage can occur in fields without proper training, leading to engineering errors. -
Confusing AC and DC Motor Principles:
Many individuals confuse AC motor principles with those of DC motors. AC motors operate under alternating current principles, where electrical current periodically reverses direction, while DC motors work with direct current where electricity flows in one direction. This misunderstanding can obstruct effective motor selection for various applications. -
Associating with Only Magnetic Fields:
Some people mistakenly believe the right-hand rule only relates to magnetic fields. While it helps visualize magnetic field direction, it also applies to determining motion direction and torque generated in motors. Users overlook this, limiting the practical utility of the rule. -
