State Fleming\'s Left hand rule... |
|
Answer» Fleming\'s left hand rule states that stretch out the forefinger, middle finger and thumb perpendicular to each other. If the forefinger gives the direction of magnetic field ,the middle finger gives the direction of current ,then the thumb will gives the direction of force. When we stretch our first three fingers.. such they they r mutually perpendicular to each other..then forefinger shows direction of magnetic field..middle finger shows direction of current.. Strecth your thumb ,middle finger & for finger in such a way that they r mutually perpendicular to each other,with fore finger as magnetic field, middle finger as the induced current, then thumb shows the force direction. I\'m unable to understand.. See in NCERT |
