The induced current in the circular loop flows clockwise . A flat, circular, copper loop of radius r is at rest in a uniform magnetic field of magnitude B that extends far beyond the edge of the loop.
What is the direction of the induced current in the circular loop?
The direction of the induced current in the circular loop is counterclockwise . In c, the current is constant implying that there is no change in flux. Therefore, the induced current in the circular loop is zero.
What is the magnitude of induced current in the circular loop ABCD of radius r?
As current through wire KL is steady, magnetic flux linked with the loop ABCD is cosntant. As there is no charge in magnetic flux, induced current = 0 .
What is the direction of the current in the loop?
By the right-hand rule, on the surface of the loop the magnetic field will have a direction towards you (going out of the paper). As it is increasing, by Lenz’s law a current opposed to this change has to appear: the current in the loop is clockwise .
What is the direction of the induced current in the circular loop due to the current increasing through the straight conductor?
The induced current is clockwise . There is no change in magnetic flux through the loop. No current is induced in the loop because the magnetic flux is constant. Using Right-hand rule for straight conductors: An increasing magnetic field is directed into the page through the loop.
How do you find the direction of induced current class 10?
Fleming’s right hand rule : Stretch the first three fingers of the right hand, mutually perpendicular to each other such that the fore-finger gives the direction of the magnetic field and the thumb points the direction of the motion of a conductor. Then, the middle finger will give the direction of the induced current.
What is magnitude of induced current in a circular loop of radius r If straight wire PQ carries a steady current of I ampere?
The magnitude of induced current in the circular loop (K L M N) of radius (r) if the straight wire (PQ) carries a steady current of magnitude (i) ampere is zero because there is no change in the number of magnetic field lines through the circular loop.
Is there any induced current in the circulating loop Pqrs of radius R as shown in Fig below if the straight wire AB causes a steady current of magnitude of 1ampere Why?
No current will be produced in the loop because the magnetic flux doesn’t change or there is no relative motion between the magnetic field around the conductor & the circuit loop.
What is the direction of the induced current in the loop chegg?
A clockwise current is induced in the loop.
What is induced emf and induced current?
Whenever there is a change in the magnetic flux linked with a closed circuit an emf is produced . This emf is known as the induced emf and the current that flows in the closed circuit is called induced current.
What is the direction of induced current in the metal rings 1 and 2 when current I in the wire is increasing steadily?
So, induced current will be clockwise in ring 1 and anticlockwise in ring 2.
What is the direction of induced current in the loop when the current in the wire AB is decreasing?
In the given figure current from A to B in the straight wire is decreasing. The direction of induced current in the loop is A anticlockwise .
Is the induced current clockwise or counterclockwise?
The induced current will be counterclockwise (ccw). As the bar moves upward through the constant magnetic field region, the area of the loop decreases, so the flux through the loop decreases. By Lenz’s law, any induced current will tend to oppose the decrease.
What is the direction of induced current in the resistance R?
In the north direction .
What is induced current class 10th?
Induced current means current produced by movement of wire (conductor) in a magnetic field or change in magnetic field (This current is produced without any physical contact between wire and magnet)
When the current in the wire is increasing the induced current in the loop is?
If the current increases continuously, then the direction of the induced current in the loop is clockwise .
What will be the direction of induced current when a bar magnet is swiftly moved away from the coil when seen from magnet side )?
(i) If seen from the right hand side, current flows clockwise when South-pole moves towards the coil. (ii) If seen from the left hand side, current flows clockwise when N-pole of the bar magnet moves away from the coil.
What are induced current?
Induced current: It is the current that is induced in a conducting loop which is exposed to a changing magnetic field is known as induced current. ... -By changing the strength of the magnetic field. -Moving the conductor in and out of the magnetic field. -Altering the distance between magnet and the conducting loop.
What is the direction of induced emf?
The direction of induced emf is perpendicular to the direction of magnetic field as well as the direction of velocity of the charge. This direction can be determined by right-hand rule.
Is direction of induced emf and induced current same?
Originally Answered: are the directions of induced emf and induced current same? Generally they are same .
What is the direction of induced current in metal ring placed perpendicular to the plane of paper when the current in the straight wire below it is increased gradually?
Hence the direction of current in ring-1 will be clockwise .
For ring-2, direction of magnetic field is perpendicular to the plane of paper/sheet, and directed outwards. In the same way as ring-1, the decreasing current will now make the upper face of the ring the north-pole after electromagnetic induction.
When current is increasing in the coil the direction of induced emf is dash the direction of current?
Coil means inductor where the current is flowing through it, the direction of induced emf is in the opposite direction of current which is shown in the diagram. Arrow of right side shows increment and arrow of left side shows decrement.
Which law gives the polarity of induced emf?
When an emf is generated by a change in magnetic flux according to Faraday’s Law the polarity of the induced emf is given by Len’z Law .
What is the direction of current flow in the B arm of loop?
The current flows from arm A to B arm and then C to D, the direction of flow of current in both arms is opposite . As per Fleming’s left hand rule, the force acting on arm AB pushes it down while the force acting on CD pushes it upwards. Thus, the coil and the axle rotate anticlockwise.
When the rate of change of current is unity the induced emf is equal to *?
then the induced emf = coefficient of self-induction .
i.e. the coefficient of self induction of a coil is equal to the flux linked with the coil when the current in it is 1 amp. Hence coefficient of self induction is equal to the emf induced in the coil when the rate of change of current in the coil is unity.
When the rate of change of current is unity the induced emf is equal to?
So, when rate of change of current is equal to unity, emf is equal to coefficent of self inductance .
