Which rule of Fleming can be used to determine the direction of induced 1 current in the secondary coil if current in the primary coil is changed?
Fleming’s Right hand rule – If the forefinger, second (central) finger and thumb of the right hand are stretched at right angles to each other, with the forefinger in the direction of the field, the thumb in the direction of the motion of the wire then the induced current in the wire is in the direction of the second …
Which law determines the direction of induced current in a coil?
Lenz’s law is used for determining the direction of induced current. Lenz’s law of electromagnetic induction states that the direction of induced current in a given magnetic field is such that it opposes the induced change by changing the magnetic field.
What will be the direction of induced current?
It is “clockwise” when you look at your hand thumb-on, or when you look at the change pointing towards you. The direction of this magnetic field looks like this: point your right thumb in the direction of the current, then your fingers curl in the direction of the induced magnetic field.
How do you increase the strength of induced current in a coil state the rule to determine the direction of induced current?
Which rule is used to find the direction of induced emf in a coil?
The direction of induced emf is determined by right hand rule. As per the the rule, if the thumb is pointed in the direction of motion of the conductor and the first finger is pointed in the direction of the magnetic field (north to south), then the second finger represents the direction of the induced current.
Which rule is used to find the direction of induced emf in DC?
Fleming’s right-hand rule (for generators) shows the direction of induced current when a conductor attached to a circuit moves in a magnetic field.
Which law gives the direction of induced emf in LVDT?
Explanation: Fleming’s left hand rule stated that if the index finger points towards magnetic flux, the thumb towards the motion of the conductor, then the middle finger points towards the induced emf.
How do you determine the direction of an induced emf?
Stretch the forefinger, middle finger and the thumb of the right hand mutually perpendicular to each other. If the force finger points in the direction of the magnetic field, the thumb gives the direction of the motion of the conductor then the middle finger gives the direction of the induced current.
What is Faraday’s second law of electromagnetic induction?
Faraday’s second law of electromagnetic induction states that. The induced emf in a coil is equal to the rate of change of flux linkage. The flux is the product of the number of turns in the coil and the flux associated with the coil.
