फ्लेमिंग का वाम हस्त नियम 3D में
Fleming's left-hand rule is hard to apply from a flat textbook diagram because the whole point is that the three quantities are mutually perpendicular. This 3D simulation lets you rotate a hand model together with the field, current and force vectors until the relationship clicks.
इस सिमुलेशन का उपयोग कैसे करें
- Rotate the 3D scene to view the vectors from any direction
- Reverse the current or the field direction
- Change the angle between the wire and the field
क्या देखें
- Reversing either the field or the current flips the force; reversing both restores it
- Force is greatest when current runs perpendicular to the field
- No force acts when the wire lies along the field direction
इसके पीछे की भौतिकी
A wire carrying current I across a magnetic field B experiences a force F = BIL·sinθ, directed perpendicular to both. With the left hand, the first finger points along the field, the second along the conventional current, and the thumb then gives the direction of the resulting motion. When current runs parallel to the field, sinθ is zero and there is no force at all.
