The lines of magnetic flux density passing upward through the center of the driving coil are trapped between the driver coil and the disk as they turn radially outward. These lines are sketched in Fig. 10.2.4. In the terminology introduced with Example 9.7.4, the disk is the secondary of a transformer.
The apparatus used by Faraday to demonstrate that magnetic fields can create currents is illustrated in Figure (PageIndex{1}). When the switch is closed, a magnetic field is produced in the coil on the top part of the iron ring and transmitted to the coil on the bottom part of the ring.

A changing magnetic field induces a current in a conductor. For example, if we move a bar magnet near a conductor loop, a current gets induced in it. Faraday''s law states that . The E.M.F. $mathcal{E}$ induced in a conducting loop is equal to the rate at which flux $phi$ through the loop changes with time. Along with Lenz''s law,

When a conductor cuts through field lines, a potential difference is induced across the ends of the conductor. This is called electromagnetic induction. The size of the induced potential difference is determined by: The strength of the field lines – i.e. the strength of the magnet How many lines are cut – the speed of the magnet How quickly

Yes, flux cutting and flux linking are different. There are two basic ways of producing an induced emf: As the coil rotates anticlockwise around the central axis which is perpendicular to the magnetic field, the wire loop cuts the lines of magnetic force set up between the north and south poles at different angles as the loop rotates.

I know that one can explain motional emf by considering a free electron in the conductor and finding the force it experiences in the magnetic field. but I have read some explanations which involve ''cutting'' of magnetic flux. The method seems correct, but I am unable to understand it entirely.
Capacitors and cutting magnetic flux lines the capacitor plates. Electrical field lines in a parallel-plate capacitor begin with positive charges and end with negative charges. The magnitude of the electrical field in the space between the plates is in direct proportion to the
Increasing and decreasing magnetic flux. The magnetic flux increases as the angle between the field lines and normal decreases. This means the magnetic flux is: maximum = BA when cos(θ) =1 therefore θ = 0 o. The

Magnetic field lines of a single circular coil are added up together to make to make the field lines of a solenoid. Factors Affecting the Magnetic Field Strength. The strength of the magnetic field of a solenoid can be increased by: Adding a core made from a ferrous (iron−rich) material eg. an iron rod. Adding more turns in the coil
For a straight wire moving perpendicular to a uniform magnetic field in velocity v, $$ε=dfrac{Delta Phi}{Delta t}=dfrac{BLv Delta t}{Delta t}$$ So the induced e.m.f in the conductor as it moves through the magnetic field is: $ε = BLv$. However, isn''t the rate of magnetic flux cut by the straight wire itself zero? The straight wire has

When a conductor moves through a magnetic field, there will be a generated motional emf. This is one example of Faraday''s Law and it arises from the magnetic force (??). The voltage generated in a length of wire, presuming that the entire length moves through a uniform field, is given below.
Increasing and decreasing magnetic flux. The magnetic flux increases as the angle between the field lines and normal decreases. This means the magnetic flux is: maximum = BA when cos(θ) =1 therefore θ = 0 o. The magnetic field lines are perpendicular to the plane of the area; minimum = 0 when cos(θ) = 0 therefore θ = 90 o. The magnetic

I was originally under the impression that flux cutting was when there was relative motion between a conductor and a magnet and linking was when there was a change in the magnetic flux density. After reading, it seems that flux linking is when a magnet is moving and a conductor is still whilst flux cutting is the other away round.
When the flux of the primary coil in a transformer changes, the flux linked with the secondary coil changes. This is flux linking. A metal conductor moves through the magntic field of a magnet and cuts its field lines. Flux cutting. An AC-generator coil spins in a magnetic field, changing the magnetic flux through the coil.
If a conductor is situated in a time-varying magnetic field, the induced electric field gives rise to currents. From Sec. 8.4, we have shown that these currents prevent the penetration of the magnetic field into a perfect conductor. How high must be to treat a conductor as perfect?
It depends what you imagine the wire is connected to, to complete a circuit. If the whole circuit is moving (in the field), and staying the same shape, then yes there's no change in flux. But we always imagine a rectangular circuit with one edge fixed, and two edges getting longer and longer, so that the flux through the circuit is increasing!
If the velocity of the rod is perpendicular to the rod, the rod cuts the magnetic field lines (assuming they exist as lines), but if velocity is parallel to the length, it doesn't do so! I would like to know why exactly it is able to 'cut' the field, or more precisely, what it does when it cuts the field.
