Electromagnetic induction question

In summary, the conversation discusses a misunderstanding of the principle of a Hall probe and the concept of induced EMF in a coil. The speaker was confused about why the graph for the hall probe dropped off sharply towards the end and did not understand the difference between the coil graph and the probe graph. They also asked about relevant equations and laws related to induced EMF and the configuration of the magnetic field in the setup.

I seem to have a fundamental misunderstanding of the principle here.

in the previous part it was required to sketch the graph for the hall probe. I knew since the speed was constant the field was cut at a constant rate hence a straight line was needed. However I did not understand why it dropped off sharply towards the end.

For the part shown in the image, I do not understand what is different about the coil graph from the probe graph. Surely the same logic applies, same rate of movement hence same EMF? Why would the coil be different?

Look under 2. relevant equations to see what the emf is.
What does a Hall probe measure ?

(Uh-Oh, did you erase the template :)) ?)

What do the induced emf in a coil depend on?
Any law come to mind?
Formulas?
How is the magnetic field of the setup configured?
 

Related to Electromagnetic induction question

1. What is electromagnetic induction?

Electromagnetic induction is the process by which a changing magnetic field creates an electric current in a conductor. This phenomenon was first discovered by Michael Faraday in the 1830s.

2. How is electromagnetic induction used?

Electromagnetic induction has many practical applications, such as in generators, transformers, and motors. It is also used in wireless charging technology and in devices such as induction cooktops.

3. What factors affect the strength of induced current?

The strength of the induced current depends on the strength of the magnetic field, the speed at which the magnetic field changes, and the number of turns in the conductor. Additionally, the material and shape of the conductor can also affect the induced current.

4. What is the difference between electromagnetic induction and electromagnetic radiation?

Electromagnetic induction involves the creation of an electric current through a changing magnetic field, while electromagnetic radiation is the emission of electromagnetic waves, such as light or radio waves, from a source. They are two different processes, but both involve the interaction of electricity and magnetism.

5. Can electromagnetic induction be used to generate electricity from renewable sources?

Yes, electromagnetic induction is a key principle in the generation of electricity from renewable sources such as wind and hydro power. In these systems, a rotating turbine is used to create a changing magnetic field, which induces an electric current in a conductor, producing electricity.
