Abstract:
The purpose of this experiment is to answer Faraday’s question as to whether a magnetic
field could induce an electric current. His hypothesis was that a current can be induced by the
magnetic field. This question was answered using an electromagnetic induction ring, which was
made by wrapping coils of wire around an iron ring and placing an aluminum ring on top. The
aluminum plate levitated, proving faraday’s hypothesis. The plate levitated because of the
changing magnetic fields inducing an electric current, which then induced a magnetic field
causing the plate to levitate. So, the experiment successfully proved that magnetic fields could
induce electric currents.

Introduction:
The purpose of this experiment is to prove Michael Faraday’s hypothesis that a magnetic
field could generate electric current. It had already been known that electric currents created
magnetic fields, but whether the reverse was true was still in question. To prove this, faraday
wrapped two coils of insulated wire around an iron ring, and when he connected a battery to one
of the coils, he noticed that it induced a brief pulse of current in the other wire. He noticed the
pulse was created because the magnetic field was changing. He also noticed that the coil repelled
each other when currents were induced because of their magnetic fields interacting. The video’s
experiment aims to demonstrate this same principal using an induction ring like Faraday’s.
Materials:
-Insulated Wire
-Metal Ring
-Battery
-Aluminum Plate

Methods:
The induction ring is made by having an iron ring wrapped by coils of insulated wire. For
this experiment, a 1 kg aluminum plate is placed on top of an induction ring. The induction ring
has a coil of thick wire, through which an alternating electric current is passed. The electric
current is 800A(Amps) with a frequency of 900Hz

Results:
When the current is passed through the wire, the aluminum plate levitates in the air:
Furthermore, when water is poured on the plate, then water immediately turns to steam:

Discussion
The experiment shown in the video is essentially just replacing the second wire of
Faraday’s original experiment, with an aluminum plate. When the current is passed through the
coil, the aluminum plate begins to levitate. This is because the current passed through the coil is
creating a changing magnetic field, which induces a current in the aluminum plate. The
aluminum plate then creates an opposing magnetic field, which is what causes it to levitate. The
experiment also showcases the high temperature of the plate by splashing water on it, which
immediately turns to steam. This is because the current in the plate releases its energy as heat,
like a toaster. Explaining why currents produce magnetic fields in the first place is a more
complicated question. It is known that the magnetic field produced by an electric current is
perpendicular to the direction of the current, hence why the plate goes straight up. However, this
is just a known property of electric currents, as it cannot be explained why exactly the movement
of electric charges creates a magnetic effect. Regardless, the results of this experiment prove our
initial hypothesis that magnetic fields can induce electric current.

Conclusion:
Overall, this experiment was successful in showcasing the principles of electromagnetic
induction. It demonstrated of the ideas Faraday introduced in his original induction ring by
recreating the experiment in a way gives a clear visual of how magnetic fields interact. Faraday’s
discovery that magnetic flux could generate electricity was monumental because it proved that
mechanical energy could be turned into electrical energy. This opened many possibilities for how
electrical energy could be applied, increasing the efficiency of battery technology for example.
Electromagnetism and its applications are essential to our lives in ways that never realize, and
electromagnetic induction was just the steppingstone to many incredible innovations to come; it
is used in broadcasting, Wi-Fi, cellphone communication, and cooking just to name a few.
