A current can be induced in a conducting loop if it is exposed to a changing magnetic field. A current can be induced in a conducting loop if it is exposed to a changing magnetic field.Current is induced in the loop due to electromagnetic induction when the magnetic flux through it changes. When they move with same velocity, their relative displacement is zero. Hence, magnetic flux does not change and no current is induced.

Which of the following cases current will be induced in the circular loop?
Current is induced in the loop due to electromagnetic induction when the magnetic flux through it changes. When they move with same velocity, their relative displacement is zero. Hence, magnetic flux does not change and no current is induced.
What are the three ways to induce electromagnetic current flow in a conductor?
What are the three ways to induce electromagnetic current flow in a conductor? 1) Move the conductor through a stationary, unchanging strength magnetic field. 2) Move the magnetic lines of force through a stationary conductor with an unchanging strength magnetic field.
What is the cause of induced current in a coil?
The change in magnetic field lines in a coil is the cause of induced electric current in it.
What materials are needed to induce induced current?
The current is said to be induced in the conductor by the magnetic field. One requirement for this electromagnetic induction to take place is that the conductor, which is often a piece of wire, must be perpendicular to the magnetic lines of force in order to produce the maximum force on the free electrons.

What is induced electric current?
Induced electric current is the electric current that originates in a conductor by changing the magnetic field around the conductor. Explanation. The change in magnetic field lines in a coil is the cause of induced electric current in it, and this phenomenon is known as Electromagnetic induction.
Which of the following moves induced voltage can be in a wire by?
Faraday’s Law tells us that inducing a voltage into a conductor can be done by either passing it through a magnetic field, or by moving the magnetic field past the conductor and that if this conductor is part of a closed circuit, an electric current will flow.
Which of the following is needed to induce current in a solenoid?
The magnet will induce a current in any loop through which it passes. If the solenoid is a single piece of conductive material, a current induced in one loop will produce current throughout the whole thing. This current is due to changing magnetic flux in the loop.

Which of the following will not induce a current in the loop?
only when the current in the first coil changes. Which of the following will not induce a current in the loop? Moving the loop in a direction parallel to the wire.
In which of the following cases the induced current in the loop will not be obtained *?
In this case, magnetic flux linked with the loop does not change, and hence induced current shall not be obtained.
What will not cause current to be induced in loop?
As the loop enters, the induced emf creates a CCW current while as the loop leaves the induced emf creates a CW current. While the loop is fully inside the magnetic field, there is no flux change and therefore no induced current.
Which of the following involves electromagnetic induction?
The correct answer is Magnetising an iron piece by a bar magnet. Magnetizing an iron piece with a bar magnet makes use of electromagnetic induction.
How does a magnet induce electric current?
Magnetic fields can be used to make electricity
Moving magnetic fields pull and push electrons. Metals such as copper and aluminum have electrons that are loosely held. Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current.
Which material can be a conductor for an electromagnet?
electromagnet: A magnet made of an insulated wire coiled around an iron core (or any magnetic material such as iron, steel, nickel, cobalt) with electric current flowing through it to produce magnetism.
On what factors induced current depends?
Answer. The strength of induced current depends on the strength of the magnetic field, the velocity at which the coil or the magnet is being moved and the length of the conductor which is perpendicular to the direction of the motion and finally the resistance of the conductor.
What are the factors that affect induced current?
- The number of turns of the coil:As the number of turns increases, the magnitude of the induced current increases.
- The speed of the relative motion of the conductor and the magnetic field: As the speed of the relative motion of the magnet increases, the magnitude of the induced current increases.
What are the three factors that determine the amount of induced current?
…
The size of the voltage can be varied by three factors:
- The size of the magnetic field. …
- The active length of the conductor. …
- The speed at which the conductor passes through the field.

Which of the following is produced around a conductor when current is flowing through the conductor?
Whenever current travels through a conductor, a magnetic field is generated. Whenever current travels through a conductor, a magnetic field is generated, a fact famously stumbled upon by Hans Christian Ørsted around 1820. Depending on the shape of the conductor, the contour of the magnetic field will vary.
Can magnetic flux induce current to flow?
Either moving a wire through a magnetic field or (equivalently) changing the strength of the magnetic field over time can cause a current to flow.
