Electromagnetic induction is the process of using a changing magnetic field to induce voltage in a conductor. It was discovered in 1831 by Michael Faraday, who found that a changing magnetic field can generate an electric current in a nearby wire. Electromagnetic induction underlies many electric technologies like generators, transformers, and induction cooktops. It works through Faraday's law, which states that a time-varying magnetic field produces an induced electromotive force in any nearby conductor.
1. Electromagnetic induction occurs when a changing magnetic flux induces an electromotive force (emf) in a circuit. This was discovered by Faraday through his experiments.
2. Faraday's laws of induction state that an emf is induced in a circuit when the magnetic flux through the circuit changes, and that the magnitude of this induced emf is proportional to the rate of change of the magnetic flux.
3. Lenz's law describes the direction of the induced current: the current will flow in a direction that creates its own magnetic field to oppose the original change in magnetic flux that caused it. This ensures the conservation of energy.
Breast cancer develops from breast tissue and is one of the most common types of cancer in women. Some signs and symptoms include a lump in the breast, changes to the skin on the breast, or fluid coming from the nipple. Risk factors include female sex, older age, family history and certain genetic mutations. Diagnosis involves exams, mammograms, and other scans. Treatment options include surgery to remove tumors, medication like chemotherapy or hormone therapy, and radiation therapy.

Electromagnetic induction causes a voltage to be induced in a conductor that is moving through a magnetic field or when a magnetic field is moving relative to a stationary conductor. This principle allows for technologies like electric generators, electric motors, magnetic recording/data storage, and transformers. The induced voltage is proportional to the rate of change of the magnetic flux through the conductor based on Faraday's Law of Induction.

The document is a certificate for a student named M.Ragul from grade 12 who completed a work education project on building a perpetual energy generator. The project was guided by Mr. Srikanth and fulfilled the requirements of the CBSE curriculum for the 2017-2018 academic year. The student thanks their principal, physics teacher, parents, classmates and laboratory assistant for their support and help with the project. The objective was to build a cheap perpetual energy generator using magnetic and electric fields. It works by using electromagnetic induction - an initial energy supply spins an iron nail disc near a magnet, and the changing magnetic flux induces a current to continue rotating the disc without further input.
Today large number of new technologies depends on electrical supply system, so complexity of
wires is very high. In this project, as requirement of wireless electrical power system, project
team present an analysis the concept of cable less transmission i.e. Power without the usage of
any kind of the electrical conductor or wires. Transmission or distribution of 50 or 60 Hz
electrical energy from the generation point to the consumers end without any physical wire has
yet to mature as a familiar and viable technology.
Our team chose to project the feasibility of wireless power transmission through
inductive coupling. This consists of using a transmission and receiving coils as the coupling
antennas. Although the coils do not have to be solenoid they must be in the form of closed loops
to both transmit and receive power. To transmit power an alternating current must be passed
through a closed loop coil. The alternating current will create a time varying magnetic field. The
flux generated by the time varying magnetic field will then induce a voltage on a receiving coil
closed loop system. This seemingly simple system outlines the major principle that our research
investigated. The primary benefits to using inductive coupling are the simplicity of the
transmission and receiving antennas, additionally for small power transmission this is a much
safer means of conveyance. To demonstrate the success of our the teams we created a receiving
circuit to maximize the amount of received power and light an LED at a distance up to two feet.
We were able to create both transmission and receiving circuits capable of transmitting the
necessary power to light an LED in a pulsed mode. On average with transmitting one watt of
power the receiving circuit was able to receive 100 micro-watts of power. While the efficiency of
the system is extremely low, approximately 0.01% with some improvements we feel certain the
efficiency could be greatly improved. Furthermore, as the transmission distance is decreased the
efficiency of any system using inductive coupling improves exponentially.

Decolonizing Universal Design for LearningFrederic Fovet
UDL has gained in popularity over the last decade both in the K-12 and the post-secondary sectors. The usefulness of UDL to create inclusive learning experiences for the full array of diverse learners has been well documented in the literature, and there is now increasing scholarship examining the process of integrating UDL strategically across organisations. One concern, however, remains under-reported and under-researched. Much of the scholarship on UDL ironically remains while and Eurocentric. Even if UDL, as a discourse, considers the decolonization of the curriculum, it is abundantly clear that the research and advocacy related to UDL originates almost exclusively from the Global North and from a Euro-Caucasian authorship. It is argued that it is high time for the way UDL has been monopolized by Global North scholars and practitioners to be challenged. Voices discussing and framing UDL, from the Global South and Indigenous communities, must be amplified and showcased in order to rectify this glaring imbalance and contradiction.
This session represents an opportunity for the author to reflect on a volume he has just finished editing entitled Decolonizing UDL and to highlight and share insights into the key innovations, promising practices, and calls for change, originating from the Global South and Indigenous Communities, that have woven the canvas of this book. The session seeks to create a space for critical dialogue, for the challenging of existing power dynamics within the UDL scholarship, and for the emergence of transformative voices from underrepresented communities. The workshop will use the UDL principles scrupulously to engage participants in diverse ways (challenging single story approaches to the narrative that surrounds UDL implementation) , as well as offer multiple means of action and expression for them to gain ownership over the key themes and concerns of the session (by encouraging a broad range of interventions, contributions, and stances).

CONCLUSION
Faraday’s Law of Electromagnetic Induction, first
observed and published by Michael Faraday in the
mid-nineteenth century, describes a very
important electromagnetic concept. Although its
mathematical representations are cryptic, the
essence of Faraday’s is not hard to grasp: it relates
an induced electric potential or voltage to a
dynamic magnetic field. This concept has many
far-reaching ramifications that touch our lives in
many ways: from the shining of the sun to the
convenience of mobile communications, to
electricity to power our homes. We can all
appreciate the profound impact Faraday’s Law has
on us.
