How would you find the direction of the electron flow in an armature located in a magnetic field?
- Flemings left hand rule.
- Flemings right hand rule.
- Maxwells corkscrew rule.
Explanation
A current-carrying armature in a magnetic field experiences a force, which is motor action, so Fleming's left-hand rule applies to find the relevant direction. The right-hand rule is reserved for generator action where motion induces current, and the corkscrew rule only gives the field around a wire.
boholbo asking:
The question asks 'Fleming's right hand rule', because the direction of the electron is it. If the question wants 'Fleming's left hand rule' as an answer, then not 'the direction of the electron flow', but 'the direction of the motion' is suitable.
